The invention discloses an array substrate, a display device and a manufacturing method thereof. By setting a pixel area surrounded by first and second common electrode lines on the array substrate, scanning lines and data lines are arranged on the center line of the pixel area. And the active element is formed in the intersection area, the pixel electrode is connected to the storage electrode and the common electrode of the first metal layer through the contact hole to form a storage capacitor, and before the formation of the pixel electrode, a black organic insulating layer is formed on the array substrate, through half-tone Mask plate or gray tone mask plate photolithography process, and form a first height pattern and a second height pattern, wherein the first height pattern is a support column, and the second height pattern is a black matrix. The display device of the present invention also includes a color filter substrate and a display medium sandwiched between the two substrates. The invention can reduce one production process, lower the process cost and improve the qualified rate of products.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a structure of a display device and a manufacturing method thereof, and a manufacturing method thereof. Background technique [0002] figure 1 It is a schematic cross-sectional view of a display device in the prior art, such as figure 1 As shown, the photoelectric display device includes an array substrate 11, a color filter substrate 13, and a display medium layer 13 sandwiched between the two substrates. The backlight 14 is incident from the side of the array substrate 11, and the The array side polarizing plate 115 and the color filter side polarizing plate 124 are respectively pasted on the color filter substrate. [0003] Among them, the array substrate 11 generally includes a gate metal layer 111, a gate insulating layer, a semiconductor layer 112, a source-drain metal layer 113, a source-drain insulating layer, an organic insulating layer, an...
