Display device

A display device, comprising:

• an array substrate including a display region arranged with pixels and a peripheral region outside the display region;
• a counter substrate facing the array substrate;
• and
• a liquid crystal layer between the array substrate and the counter substrate,
• wherein the display region includes a plurality of scanning signal lines extending in a first direction and arranged in a second direction intersecting the first direction, and a plurality of data signal lines extending in the second direction and arranged in the first direction,
• wherein the peripheral region includes a plurality of first wirings connecting a scanning signal line driver circuit and the plurality of scanning signal lines, and a plurality of second wirings being supplied with a certain electric potential,
• wherein each of the plurality of first wirings is arranged in parallel and extends in a diagonal direction intersecting both the first direction and the second direction,
• wherein each of the plurality of second wirings is arranged in parallel and extends in the diagonal direction intersecting both the first direction and the second direction, and in the same direction as the plurality of first wirings,
• the pixel includes a pixel electrode and a transistor connected to the pixel electrode,
• the array substrate includes a planarization layer extending over the display region and the peripheral region,
• the pixel is arranged in a region where the planarization layer is removed,
• the plurality of first wirings and the plurality of second wirings are embedded in the planarization layer,
• the planarization layer has a stripe pattern that is removed in the peripheral region outside of the plurality of first wirings and the plurality of second wirings, and
• the stripe pattern is overlapped with the plurality of first wirings and the plurality of second wirings.
