Liquid crystal display comprising a pixel electrode having a transverse stem, a longitudinal stem, and a plurality of minute branches
A liquid crystal including: a first substrate; a pixel electrode disposed on the first substrate and including a first subpixel electrode and a second subpixel electrode disposed in one pixel area; a second substrate facing the first substrate; and a common electrode disposed on the second substrate, wherein an area of a region occupied by the first subpixel electrode is less than an area of a region occupied by the second subpixel electrode. Each of the first and second subpixels has a cross-shaped stem and minute branches extending from it to improve side visibility quality and gray scale uniformity.
1. A liquid crystal display comprising:
a first substrate;
a gate line and a data line disposed on the first substrate;
a pixel electrode disposed on the first substrate and connected to the gate line and the data line, the pixel electrode comprising:
a transverse stem;
a longitudinal stem; and
a plurality of minute branches extending from the transverse stem and the longitudinal stem;
a second substrate facing the first substrate;
a liquid crystal layer comprising liquid crystal molecules disposed between the first substrate and the second substrate; and
a common electrode disposed between the liquid crystal layer and the second substrate,
wherein:
a width of the transverse stem of the pixel electrode is greater than the width of the longitudinal stem of the pixel electrode;
the transverse stem comprises a plurality of first cutouts parallel to the minute branches; and
the common electrode comprises a second cutout formed at a position corresponding to the longitudinal stem.
2. The liquid crystal display of claim 1 , further comprising
an alignment layer disposed on at least one of the first substrate and the second substrate,
wherein:
the liquid crystal molecules are arranged substantially perpendicular to a surface of the first substrate and the second substrate in the absence of an electric field between the pixel electrode and the common electrode; and
at least one of the liquid crystal layer and the alignment layer comprises a light reactive material.
