Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163718
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent a decrease in transmittance and improve viewing angle characteristics while suppressing an increase in manufacturing cost in a fringe field switching (FFS) liquid crystal display device that has a picture element comprising three pixels of red, green, and blue which are arranged such that the longitudinal direction and the transverse direction of the pixels are the extending direction of the scanning line and the extending direction of the data line, respectively, and has a triple gate structure in which the three pixels in the picture element are driven by three mutually different scanning lines. In the FFS liquid crystal display device having a triple gate structure, a positive liquid crystal is used for a liquid crystal (150) interposed between a TFT array substrate (100) and an opposite substrate (200). Each of the pixels (10) has a horizontally-long laterally elongated shape with a slit, which is arranged in a pixel electrode (12) or a common electrode (13), extending along the horizontal direction. Further, a biaxial retardation film (503) is provided on the surface of a liquid crystal display panel on the backlight side, i.e. on the TFT array substrate (100) side.
