Abstract
In this display device, an electrode layer for an upper electrode and a lower electrode is formed on an array substrate via a dielectric film, one of the upper electrode and the lower electrode is a pixel electrode, the other thereof is a common electrode, and an opening portion for generating horizontal electric field in a liquid crystal layer is formed in accordance with a shape of the electrode layer in a plan view. A CF substrate has a light-shielding film (BM) including a lateral BM portion. The opening portion has a plurality of slits in an X direction, and an end portion of an outermost slit in a Y direction is concealed by the lateral BM portion overlapped in a Z direction.
Claims17
A display device comprising:
- a first substrate;
- a liquid crystal layer arranged on the first substrate;
- a plurality of pixels arranged on the first substrate, the pixels comprising:
- a first pixel;
- and
- a second pixel adjacent to the first pixel in a first direction;
- a common electrode arranged between the first substrate and the liquid crystal layer, the common electrode comprising:
- a first base portion extending in a second direction crossing the first direction and arranged in the first pixel;
- a second base portion extending in the second direction and arranged in the second pixel;
- a third base portion extending in the second direction and arranged between the first pixel and the second pixel;
- a first connecting portion extending in the first direction, the first connecting portion coupling the first base portion to the third base portion and the second base portion;
- a first projecting portion extending from the third base portion in a direction from the third base portion to the first base portion, the first projecting portion being separated from the first base portion;
- a second projecting portion extending from the third base portion in a direction from the third base portion to the first base portion, the second projecting portion being separated from the first base portion;
- a third projecting portion extending from the first base portion in a direction from the first base portion to the third base portion, the third projecting portion being separated from the third base portion, the third projecting portion being arranged between the first projecting portion and the second projecting portion in the second direction;
- and
- a fourth projecting portion extending from the third base portion in a direction from the third base portion to the second base portion, the fourth projecting portion being separated from the second base portion;
- a first pixel electrode arranged between the first substrate and the liquid crystal layer in the first pixel, the first pixel electrode overlapping the first projecting portion, the second projecting portion and the third projecting portion in a plane view;
- and
- a light shielding layer overlapping the first connecting portion in the plane view.
