Embodiment Construction

[0023] refer to figure 2 and image 3 , figure 2 It is a schematic flow chart of the first embodiment of the manufacturing method of the display panel of the present invention, image 3 yes figure 2 Schematic diagram of the structure of the display panel manufactured by the first embodiment of the manufacturing method shown. Manufacturing Method First Embodiment The display panel 300 is manufactured, and the first embodiment includes the following steps.

[0024] S201: Provide a substrate.

[0025] Generally, the substrate 30 is made of light-transmitting materials such as glass.

[0026] S202: forming a source, a drain and a channel on the substrate.

[0027] A source 310 , a drain 311 and a channel 33 are formed on the substrate 30 . The source 310 and the drain 311 are conducted through the channel 33 , and electron-hole pairs flow in the channel 33 to form a current.

[0028] In this step S202, the channel 33 can be made to be a layer closer to the substrate 30,...

Abstract

The invention discloses a display panel and a manufacturing method thereof. The manufacturing method of the display panel includes the steps of: providing a substrate, forming a source electrode, a drain electrode and a channel on the substrate; depositing a first insulating layer on the substrate; A plurality of color photoresists arranged at intervals are formed on an insulating layer, so that the source, drain and channel are located between two adjacent color photoresists; the gate and the common electrode are formed by the same process, and the gate Formed on the first insulating layer between two adjacent color photoresists, the common electrode is formed on the color photoresist; a second insulating layer is formed on the gate and the common electrode, and the second insulating layer has a connected source A through hole; a pixel electrode is formed on the second insulating layer, the pixel electrode is in contact with the source through the through hole, and the pixel electrode further forms a storage capacitor with the common electrode. The storage capacitance can be increased by the manufacturing method of the invention, and the leakage condition of the pixel electrode can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In the current field of display technology, COA (Color Filter on Array) technology is developing rapidly. COA is the process technology of making color photoresist on TFT substrate. Using this process technology will not produce alignment errors between pixels and color photoresist, and The parasitic capacitance can be reduced, and the display panel can have higher resolution and pixel aperture ratio. [0003] see figure 1 , figure 1 It is a structural schematic diagram of a display panel manufactured by the current COA process. In the prior art, the gate 12, the common electrode 13, the first insulating layer 14, the channel 15, the source / drain 16, the color photoresist 17 are sequentially formed on the substrate 11, and finally the pixel electrode 18 is formed, wherein the color light The re...
