Array substrate and display device

A display device, comprising an array substrate, a counter substrate arranged opposite to the array substrate, and a liquid crystal layer arranged between the array substrate and the counter substrate,

• wherein the array substrate comprises a base substrate, and a plurality of gate lines extending in a first direction and a plurality of data lines extending in a second direction arranged on the base substrate, wherein each gate line crosses the plurality of data lines to define a plurality of sub-pixels, wherein the array substrate further comprises:
• a plurality of touch signal lines extending in the second direction and arranged in light shielding regions of the sub-pixels;
• a plurality of touch electrodes insulated from each other and each coupled to at least one touch signal line;
• and
• a plurality of metal pattern units corresponding to the sub-pixels respectively and each arranged in the light shielding region of the corresponding sub-pixel,
• wherein the metal pattern unit comprises a first metal strip arranged on at least one side of the data line and extending in the second direction, an overlapping area between an orthogonal projection of the first metal strip onto the base substrate and an orthogonal projection of the touch signal line onto the base substrate is A, and a ratio of the overlapping area A to an area of the orthogonal projection of the touch signal line onto the base substrate is greater than a threshold;
• wherein the orthogonal projection of the first metal strip onto the base substrate does not overlap an orthogonal projection of the data line onto the base substrate;
• wherein in a direction parallel to the base substrate and perpendicular to the second direction, a minimum distance between a boundary of the orthogonal projection of the first metal strip onto the base substrate and a boundary of the orthogonal projection of the data line onto the base substrate is 2.1 μm to 8 μm.
