The disclosure relates to an array substrate, a manufacturing method thereof, and a
display device, and relates to the technical field of
liquid crystal display. The array substrate includes a base substrate, a
thin film transistor layer on the base substrate, a
passivation layer on the
thin film transistor layer, a color resistance layer on the
passivation layer, and a color resistance layer on the color resistance layer for An organic insulating layer that isolates the color
resist layer. On the one hand, the present disclosure manufactures the color-
resist layer in the array substrate, which can effectively solve the problems of light leakage caused by alignment deviation in the process of aligning
liquid crystal display devices, thereby improving the display
aperture ratio; on the other hand, the organic insulating layer is used as the The
isolation layer of the color-resistive layer can improve the
isolation effect, and can also avoid the formation of the
isolation layer in the CVD chamber in the related art, thereby causing the
diffusion of the color-
resistor to contaminate the CVD chamber, thereby prolonging the maintenance period and reducing the maintenance cost.
