The present invention relates to a liquid crystal display technology field, and more particularly to a transflective liquid crystal display panel and a liquid crystal display device having the liquid crystal display panel.
Because the liquid crystal molecules cannot emit light, a liquid crystal display panel requires a light source to display an image. According to the type of the light sources, a liquid crystal display panel can be divided into a transmissive type, a reflective type or a transflective type. Wherein, the transmissive type liquid crystal panel utilizes a backlight source, and a pixel electrode is a transparent in order to facilitate a light passing through a liquid crystal layer to display an image. The reflective type liquid crystal panel utilizes a front light source or an external light source, and a reflective layer will reflect a light so that the light can pass through the liquid crystal layer to display an image. The transflective type liquid crystal display panel can be regarded as a combination of the transmissive type and the reflective type so that the transflective type liquid crystal display panel can utilize a backlight source, a front light source or an external light source at the same time to display an image.
The transflective type liquid crystal display panel has advantages of the transmissive type and the reflective type so that the transflective type cannot only display a bright image in a dark environment for an indoor use, but also be applied in an outdoor use. For obtaining an even reflection effect at every viewing angle for an observer, the reflective layer of the conventional transflective type liquid crystal display panel adopts a reflection method of diffuse reflection such that a reflection surface of the reflective layer has a concave and convex structure in order to realize the diffuse reflection. The manufacturing method of the reflective layer generally is: firstly, manufacturing a resin layer as a base, because the reflective layer only requires disposing at a reflective region, and not requires disposing at a transmissive region, an additional photomask is required; then, performing an exposure process, a development process, and an etching process in order to form a concave and convex structure on the resin layer; the process also requires an additional photomask process; finally, forming a reflective layer on the concave and convex structure.
It can be understood that the conventional art requires two photomask processes to manufacture the reflective layer so that the manufacturing process is more and the manufacturing cost is higher. Besides, the dimensional precision of the concave and convex structure for ensuring a diffuse reflection effect should be higher so that an error is easily to generate, which will affect the reflection effect.
Accordingly, the technology problem solved by the embodiment of the present invention is to provide a liquid crystal display device and liquid crystal display panel, which can use less photomask processes to realize a transflective display effect in order to reduce the manufacturing processes, the manufacturing cost, and ensure the reflection effect at the same time.
