Abstract

Provided is a display device in which variation in white balance is suppressed even if wiring lines are arranged in pixels. The display device includes: gate lines; source lines 15 S; drive elements connected to the gate lines and the source lines 15 S; pixel electrodes connected to the drive elements; and color filters provided corresponding to the pixel electrodes. The pixel electrodes are provided in one-to-one correspondence with subpixels, and a plurality of subpixels 18 R, 18 G, and 18 B constitute one pixel. The display device further includes wiring lines L provided in a pixel region so as to extend along either the gate lines or the source lines. At least some of the wiring lines L are arranged in pixel aperture regions of the subpixels 18 . The arrangement pitch P 1 of the wiring lines L is larger than the pixel pitch (3×Sa).

Claims (40)

1. A display device comprising:

gate lines;

source lines;

drive elements connected to the gate lines and the source lines;

pixel electrodes connected to the drive elements; and

color filters of a plurality of colors provided corresponding to the pixel electrodes,

the pixel electrodes being provided in one-to-one correspondence with subpixels,

a plurality of subpixels of the plurality of colors constituting one pixel, wherein

the display device further includes wiring lines provided in a pixel region so as to extend along either the gate lines or the source lines,

at least some of the wiring lines are arranged in pixel aperture regions of the subpixels, and

an arrangement pitch of the wiring lines is larger than a pixel pitch.

2. The display device according to claim 1 , wherein the wiring lines are arranged in the pixel aperture regions of the subpixels of all of the plurality of colors.

3. The display device according to claim 1 , wherein

the wiring lines are arranged in the pixel aperture regions of the subpixels of a specific color among the plurality of colors.

4. The display device according to claim 1 , further comprising a black matrix provided corresponding to regions where the gate lines and the source lines are formed,

wherein, in each subpixel with the wiring line arranged therein, at least one of a black matrix opening length and a black matrix opening width is greater than that in each subpixel without the wiring line arranged therein.

5. The display device according to claim 1 , wherein

a size of each subpixel with the wiring line arranged therein in a width direction of the wiring line is greater than that of each subpixel without the wiring line arranged therein.

6. The display device according to claim 1 , wherein

the color filters are laid out in a stripe arrangement.

7. The display device according to claim 1 , wherein

a minimum unit of repetition of colors of the color filters includes at least two colors in an extending direction of the source lines and at least two colors in an extending direction of the gate lines.

8. The display device according to claim 1 , further comprising a gate driver for driving the gate lines,

wherein at least one of switching elements included in the gate driver are arranged in the pixel region, and

at least one of the wiring lines are connected to the switching elements.

9. The display device according to claim 8 , wherein

the switching elements included in the gate driver are each provided with an oxide semiconductor film.

10. The display device according to claim 1 , further comprising a common electrode facing the pixel electrodes,

wherein at least one of the wiring lines are connected to the common electrode.

11. The display device according to claim 1 , further comprising a touch electrode for touch detection,

wherein at least one of the wiring lines are connected to the touch electrode.

12. The display device according to claim 1 , further comprising a gate driver for driving the gate lines,

wherein the gate driver is arranged outside the pixel region in an extending direction of the source lines, and

at least one of the wiring lines connect the gate driver and the gate lines.

13. The display device according to claim 1 , wherein

the source lines and the wiring lines are formed in the same layer.

14. The display device according to claim 1 , wherein

the source lines and the wiring lines are formed in different layers.

15. The display device according to claim 1 , wherein

the drive elements are each provided with an oxide semiconductor film.
