Problems solved by technology
[0004] However, if the color resistance contained in the color resistance layer is long strip, then the AOI equipment can only grab the first set of opposite sides extending in the direction of color resistance extension
like figure 1 As shown, it shows a top view of a color-resist layer 1' with striped color-resist. The AOI equipment can only capture the first set of opposite sides A1' in one direction, and the other side perpendicular to this direction Upwards, the second set of opposite sides cannot be grabbed, and the smallest repeating unit cannot be obtained, so that optical inspection cannot be performed, resulting in an increase in defect rate, or a decrease in production capacity

The invention provides an array substrate, a display device and a manufacturing method of the array substrate. The array substrate comprises a substrate, a plurality of scanning lines and a plurality of data lines, wherein the scanning lines are arranged along a first direction and extend along a second direction; the array substrate also comprises a color resistor layer; the color resistor layer, the scanning lines and the data lines are located on the same side of the substrate; the color resistor layer comprises a plurality of different-colored strip-shaped color resistors; the strip-shaped color resistors extend along the first direction and are arranged along the second direction; a plurality of characteristic patterns arranged along the first direction are arranged in the strip-shaped color resistors; a pitch of adjacent characteristic patterns in the first direction is an integral multiple of that of two adjacent scanning lines in the first direction. The technical scheme of arranging the characteristic patterns on the strip-shaped color resistors is capable of ensuring that minimum repetition units can be captured in automatic optical detection; even if the strip-shaped color resistors are adopted, the optical detection can be carried out; the reject ratio in the production process of the array substrate is reduced; the productivity is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display device, and a manufacturing method of the array substrate, which arrange characteristic patterns on strip color resists to ensure that the smallest repeating unit is captured in automatic optical inspection. Background technique [0002] With the development of LCD (Liquid Crystal Display, liquid crystal display) technology, people have higher and higher requirements for the performance of the color-resist layer. color filter on array, the color filter is located on the array substrate) technology, that is, both the thin film transistor and the color resist layer are prepared on the same substrate. [0003] During the preparation process of an array substrate adopting a COA structure, generally, a driving device layer is first formed on the substrate, and then a color resist layer is formed on the driving device layer. Due to the low transm...
