Abstract
A display device includes a first common bus line electrically connected to common wirings, a second common bus line electrically connected to the first common bus line, and connection wirings for supplying a common voltage to the second common bus line. The second common bus line is divided into a plurality of division wirings. A column direction width of a first division wiring connected to a first connection wiring close to the first common bus line is smaller than a column direction width of a second division wiring connected to a second connection wiring far from the first common bus line.
Claims9
A display device, comprising:
- a plurality of gate signal lines each extending in a row direction;
- a plurality of data signal lines each extending in a column direction;
- a plurality of pixel regions arranged in the row direction and in the column direction in an image display region;
- a pixel electrode formed in each of the plurality of pixel regions;
- a common electrode formed in the image display region;
- a plurality of common wirings extending in the row direction, for supplying a common voltage to the common electrode;
- a first common bus line extending along an outer edge in the column direction of the image display region at a position outside the image display region, the first common bus line being electrically connected to the plurality of common wirings;
- a second common bus line extending along an outer edge in the row direction of the image display region at a position outside the image display region, the second common bus line being electrically connected to the first common bus line;
- and
- a plurality of connection wirings arranged in the row direction at positions outside the image display region, for supplying the common voltage to the second common bus line, wherein:
- the second common bus line is divided into a plurality of division wirings by a plurality of slits;
- the plurality of connection wirings comprise:
- a first connection wiring;
- and
- a second connection wiring disposed at a position farther from the first common bus line in the row direction than the first connection wiring;
- the plurality of division wirings comprise:
- a first division wiring connected to the first connection wiring;
- and
- a second division wiring connected to the second connection wiring;
- and
- a column direction width of the first division wiring is smaller than a column direction width of the second division wiring.
