LCDs have been common display devices characterized by attributes such as, low power consumption, small dimension, and light weight. A LCD generally includes a liquid crystal panel having a color film (CF) substrate and a thin film transistor (TFT) substrate opposite to the CF substrate.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Embodiments of the present invention are described in detail with the technical matters, structural features, achieved objects, and effects with reference to the accompanying drawings as follows. It is clear that the described embodiments are part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments to those of ordinary skill in the premise of no creative efforts obtained, should be considered within the scope of protection of the present invention.

FIG. 1 is a cross sectional view of the liquid crystal panel in accordance with a first embodiment. The display panel 10 includes a CF substrate 100 and a TFT array substrate 300. The CF substrate 100 includes a first substrate 110, a plurality of photo-resist units 120, and a plurality of masking units 130. The photo-resist units 120 and the masking units 130 are arranged on a surface of the first substrate 110 adjacent to the TFT array substrate 300. The photo-resist units 120 are spaced apart from each other, and the masking unit 130 is configured between the adjacent photo-resist units 120. The TFT array substrate 300 includes a second substrate 310 and a plurality of first transparent electrode units 320. The first transparent electrode units 320 are arranged on a surface of the second substrate 310 adjacent to the CF substrate 100, and the first transparent electrode units 320 are spaced apart from each other. Each of the first transparent electrode units 320 faces toward one photo-resist unit 120. A dimension of the first transparent electrode units 320 with respect to the first direction (D1) is greater than the dimension of the corresponding photo-resist units 120 with respect to the first direction (D1). In addition, one surface of the first transparent electrode units 320 facing away the second substrate 310 is a concave curved surface, wherein the first direction (D1) is parallel to the direction of the second substrate 310. In the embodiment, the masking units 130 are black matrixes to avoid mixed light and to prevent light transmission.

Each of the first transparent electrode unit 320 includes a first portion 321, a second portion 322, and a third portion 323 connected together.

The first portion 321 includes a first end 321a and a second end 321b on the surface facing away the second substrate 310, and the first end 321a is opposite to the second end 321b. The first end 321a is farther away from the second portion 322 than the second end 321b. A gap between the surface of the first portion 321 facing away the second substrate 310 and the second substrate 310 is linearly decreased along a direction from the first end 321a toward the second end 321b.

The second portion 322 includes a third end 322a and a fourth end 322b on the surface facing away the second substrate 310, and the third end 322a is opposite to the 322b is opposite to the 322b. The third end 322a is closer to the first portion 321 than the fourth end 322b. In addition, the fourth end 322b is closer to the third portion 323 than the third end 322a. The gap between the surface of the second portion 322 facing away the second substrate 310 and the second substrate 310 is the same along the direction from the third end 322a to the fourth end 322b. That is, the surface of the second portion 322 facing away the second substrate 310 is a plane.

The third portion 323 includes a fifth end 323a and a sixth end 323b on the surface facing away the second substrate 310, and the fifth end 323a is opposite to the sixth end 323b. The fifth end 323a is closer to the second portion 322 than the sixth end 323b. In addition, a gap between the surface of the third portion 323 facing away the second substrate 310 and the second substrate 310 is linearly increased along a direction from the fifth end 323a toward the sixth end 323b.

Preferably, the first portion 321 is symmetrical to the third portion 323 with respect to the second portion 322. It can be understood that, in other embodiments, the first portion 321 may be asymmetrical to the third portion 323 with respect to the second portion 322.

In one embodiment, the photo-resist units 120 include red photo-resist units, green photo-resist units, and blue photo-resist units arranged periodically on the second substrate 310 in accordance with a predetermined sequence. For instance, within the same pixel, the predetermined sequence along the first direction (D1) is the red photo-resist unit, the green photo-resist unit, and the blue photo-resist unit.

The TFT array substrate 300 further includes a plurality of second transparent electrode units 330. The second transparent electrode units 330 are closer to the CF substrate 100 than the first transparent electrode units 320. In addition, the second transparent electrode units 330 are insulated from the first transparent electrode units 320. The first transparent electrode units 320 are configured to receive a first voltage, and the second transparent electrode units 330 are configured to receive a second voltage. The second voltage loaded on the second transparent electrode units 330 cooperates with the second voltage loaded on the first transparent electrode units 320 to control the alignment of the liquid crystal molecules 500. The liquid crystal molecules are arranged between the CF substrate 100 and the TFT array substrate 300. In the embodiment, each of the first transparent electrode units 320 corresponds to two second transparent electrode units 330. The two second transparent electrode units 330 corresponding to one first transparent electrode units 320 are spaced apart from each other. In addition, the two second transparent electrode units 330 correspond to a middle of the first transparent electrode units 320.

In one embodiment, the first transparent electrode unit 320 is a pixel electrode, and the second transparent electrode unit 330 is a common electrode. In another embodiment, the first transparent electrode units 320 is the common electrode, and the second transparent electrode units 330 is the pixel electrode.

In view of the above, one surface of the first transparent electrode units 320 facing away the second substrate 310 is a concave curved surface. When the light beams enter the second substrate 310 and emit out via the first transparent electrode units 320, the light beams from two ends of the first transparent electrode units 320 are reflected into the photo-resist units 120. Conventionally, the light beams passing through two ends of the transparent electrode unit cannot pass through the black matrix, and thus the optical utilization of the liquid crystal panel is low. However, in view of FIG. 2, such problem may be solved with such configuration. Thus, the optical utilization of the liquid crystal panel 10 is high, which increases the displayed brightness of the liquid crystal panel 10.

Further, one surface of the first transparent electrode units 320 facing away the second substrate 310 is a concave curved surface. When the light beams emitting from the surface of the CF substrate 100 enter the second substrate 310, and emit out from the first transparent electrode units 320, the light beams from two ends of the first transparent electrode units 320 are reflected into the photo-resist units 120 such that the brightness of the rim of the photo-resist units 120 is greater than the brightness of the internal of the photo-resist units 120. Thus, the photo-resist units 120 including the red photo-resist units, the green photo-resist units, and the blue photo-resist unit not only increases the brightness between the above photo-resist units, but also increases the gamut of the three colors.

Further, as one surface of the first transparent electrode units 320 facing away the second substrate 310 is a concave curved surface, the electrical fields between the first transparent electrode units 320 and the corresponding second transparent electrode units 330 are blocked by two protrusion portions at two ends of the first transparent electrode units 320. Referring to FIG. 3, the impact toward the pixel in a rim has been decreased, which reduces the crosstalk issue.
