Title:
LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2011/013649
Kind Code:
A1
Abstract:
A liquid crystal display device (100) is provided with a vertically aligned liquid crystal layer (3) and a pair of photo-alignment films (12, 22). Each of a plurality of picture elements comprises four liquid crystal domains (D1-D4) which have different tilt directions of liquid crystal molecules (3a) at the application of voltage, and the four liquid crystal domains (D1-D4) are arranged in a matrix with two rows and two columns. The plurality of picture elements are even-numbered picture elements including at least four picture elements which display different colors from each other, and include a first picture element with a side parallel to a first direction having a predetermined first length (L1) and a second picture element with a side parallel to the first direction having a second length (L2) different from the first length (L1). In the first picture element, the four liquid crystal domains are arranged in a first pattern, and in the second picture element, the four liquid crystal domains are arranged in a second pattern different from the first pattern. Consequently, the increase of the cost and time required for photo-alignment processing when the 4D-RTN mode is adopted in a multiple primary color liquid crystal display device and a liquid crystal display device using a picture element multiplexing driving technique can be suppressed.
