Hereinafter, preferred embodiments of the present invention will be explained in more detail with reference to the accompanying drawings.
As shown in
A color filter 213, a common electrode 212 and a first alignment film 211 are orderly formed on an inner surface of the first substrate 21, from top to bottom. The first alignment film 211 has a first aligning direction. The LCD 2 further has a first retardation film 214 and a first polarizer 215, which are orderly disposed on an outer surface of the first substrate 21, from bottom to top.
A pixel electrode array 222 and a second alignment film 221 are orderly formed on an inner surface of the first substrate 21, from top to bottom. The second alignment film 221 has a second aligning direction, which is orthogonal to the first aligning direction of the first alignment film 211. A second retardation film 224 and a second polarizer 225 are orderly disposed on an outer surface of the second substrate 22, from top to bottom.
In addition, the pixel electrode array 222 includes a plurality of gate lines 241 that are parallel to each other and that each extend along a first direction, and a plurality of data lines 242 that are parallel to each other and that each extend along a second direction orthogonal to the first direction. The smallest rectangular area formed by any two adjacent gate lines 241 together with any two adjacent data lines 242 defines a pixel region thereat. In each pixel region, a thin film transistor (TFT) 251 is provided in the vicinity of a respective point of intersection of one of the gate lines 241 and one of the data lines 242. In each pixel region, a pixel electrode 243 is connected to the TFT 251. The gate lines 241 extend along the first direction, which is parallel to any one of the first and the second aligning directions of the first and second alignment films 211, 221.
The common electrode 212 and the pixel electrode 243 are made of a transparent conductive material, such as indium-tin-oxide (ITO) or indium-zinc-oxide (IZO).
The LCD can be manufactured by a following method. The method mainly includes the following steps:
step a: providing the first substrate 21;
step b: forming the color filter 213 and a conductive film on the first substrate 21;
step c: providing the second substrate 22;
step d: forming the plurality of parallel gate lines 241, the plurality of parallel data lines 242 orthogonal to the gate lines 241, and the plurality of TFTs 251 in the vicinity of a respective point of intersection of each of the gate lines 241 and each of the data lines 242;
step e: forming a conductive film on the second substrate 22;
step f: forming the first and the second alignment films 211, 221 respectively on the first and the second substrates 21, 22;
step g: aligning the first and the second alignment films 211, 221;
step h: adhering the first and the second substrates 21, 22, wherein the alignment directions of the first and the second alignment films 211, 221 are orthogonal to each other, and one of the alignment direction of the first and the second alignment films 211, 221 are parallel to the gate lines 241;
step i: filling liquid crystal moleculars into a space defined between the adhered first and the second substrates 21, 22;
step j: providing the first and the second retardation films 214, 224 respectively on the outer surfaces of the first and the second substrates 21, 22; and
step k: providing the first and the second polarizers 215, 225 respectively on the outer surfaces of the first and the second retardation films 214, 224.
In the step g, the first and the second alignment films 211, 221 can be aligned through rubbing method, lithography method, ion beam bombarding method and UV illuminating method.
The LCD utilizes one of the two alignment films 211, 221 having an aligning direction parallel to the gate lines 241 to realize a good viewing angle characteristics as shown in
