Embodiment 1
[0032] The TFT array substrate provided by the embodiment of the present invention, such as figure 1 , figure 2 as shown, figure 1 is a schematic top view of the structure of a pixel region of the TFT array substrate, figure 2 for figure 1 The shown cross-sectional view of the TFT array substrate along the direction A-A.
[0033] The TFT array substrate includes: a substrate 10; a gate line 11 and a gate 12 formed on the substrate 10; a gate insulating layer 20 formed on the gate line 11 and the gate 12; a semiconductor active layer formed on the gate insulating layer 20 Layer 21, formed on the source electrode 13, the drain electrode 14, and the data line 15 above the semiconductor active layer 21; there is a groove 18 on the semiconductor active layer 21 above the gate line 11; in addition, on the data line 15, the source electrode 13. A protection layer 19 is formed above the drain electrode 14; a pixel electrode 16 is formed in the area surrounded by the intersection...
Embodiment 2
[0036] Attached below Figure 3 ~ Figure 13 As shown, the method for manufacturing the TFT array substrate provided by the embodiment of the present invention will be described. In this example Figure 4 ~ Figure 13 Both are with figure 2 same section position. Such as image 3 As shown, the method steps include:
[0037] S301 , depositing a metal layer on a glass substrate, and obtaining gate lines 11 and gates 12 through a patterning process.
[0038] Such as Figure 4 As shown, the magnetron sputtering method can be used to prepare a layer with a thickness of to metal film layer. The metal material can usually be metals such as molybdenum, aluminum, aluminum-nickel alloy, molybdenum-tungsten alloy, chromium, or copper, or a combination structure of the above-mentioned thin films. Then, a plurality of horizontal grid lines 11 and gates 12 connected to the grid lines are formed on a certain area of the glass substrate 10 through a first patterning process such a...
Embodiment 3
[0057] The liquid crystal display panel provided by the embodiment of the present invention, such as Figure 14 As shown, it includes a composite TFT array substrate 80 and a color filter substrate 70, and the TFT array substrate 80 is the TFT array substrate provided in the second embodiment above, wherein the TFT array substrate 80 and the color filter substrate 70 The spacers 60 are located in the grooves 18 formed by the semiconductor active layer 41 of the TFT array substrate 80 .
[0058] In the liquid crystal display panel provided by the embodiment of the present invention, the spacer between the TFT array substrate and the color filter substrate is placed in the groove formed by the semiconductor active layer above the gate line, and when the liquid crystal panel is squeezed by external force, it can prevent The spacer falls and touches the alignment film, thereby improving the display effect of the liquid crystal panel.
[0059] In the liquid crystal display panel p...
