Abstract

Provided is a liquid crystal display capable of reducing a texture by increasing a liquid crystal control ability. The liquid crystal display includes a first electrode and a second electrode facing each other with a liquid crystal layer therebetween. The first electrode includes a horizontal extension forming a boundary between adjacent subregions and a vertical extension connected to the horizontal extension, and the horizontal extension includes a portion which has a largest width at a position proximate to the vertical extension, and which has a smaller width at a position farther from the vertical extension.

Claims18

Dependent claims

A display device, comprising:

a data line extending in a first direction;
a gate line crossing the data line and extending in a second direction;
a thin film transistor connected to the gate line and the data line;
and
a first electrode connected to the thin film transistor,
wherein:
the first electrode includes a first stem extending in the first direction and a second stem extending in the second direction;
the first stem is at an edge of the first electrode and connected to the second stem;
and
the first stem includes a first width-varying portion, the first width-varying portion has two first edges opposing each other, and one of the two first edges forms an angle which is greater than 0 degree and equal to or less than 2 degrees with respect to the first direction.
