Embodiment 1

[0050] Such as figure 1 , figure 2 As shown, the embodiment of the liquid crystal panel of the present invention includes an array substrate 1 and a box-matching substrate 9 that is box-matched with the array substrate 1. A plurality of data lines (not shown in the figure) and a plurality of gate lines are provided on the array substrate 1 3. A plurality of data lines and a plurality of gate lines 3 intersect to define a plurality of pixel regions; the array substrate 1 also includes a plurality of TFTs, the TFTs include a source 5, a drain 7 and a gate 6, an area occupied by at least one TFT The opaque region containing the channel region 4 is included in, and the distance D between the boundary of the channel region 4 and the boundary of the opaque region in the direction parallel to the liquid crystal panel is greater than or equal to the set distance d.

[0051] In an embodiment of the liquid crystal panel of the present invention, the opaque area may be formed by opaque gat...

Embodiment 2

[0079] Such as image 3 , Figure 4 As shown, in the embodiment of the liquid crystal panel of the present invention, a plurality of data lines 2 are provided on the array substrate 1, the TFT includes a gate 6 connected to the gate line 3, and the projection of the channel region of the TFT is located at the gate 6 Within the region, the boundary of the opaque region includes the boundary of the source 5 on the side away from the channel region 4 and the boundary of the drain 7 on the side away from the channel region 4.

[0080] The width of the region composed of the source electrode 5, the drain electrode 7 and the channel region 4 is greater than the width of the gate electrode 6, and the channel region 4 is a long strip region (for example, the area formed between the source electrode and the drain electrode) image 3 Exemplarily shown as a long strip area in the up and down direction).

[0081] In an embodiment of the method for manufacturing a liquid crystal panel of the pr...

Abstract

The invention relates to a liquid crystal display panel and a manufacturing method of the liquid crystal display panel. The liquid crystal display panel comprises an array substrate and a box-to-box substrate; a plurality of TFTs (Thin Film Transistors) are arranged on the array substrate; a region occupied by at least one TFT comprises a non-transparent region containing a channel region; the distance between the boundary of the channel region and the boundary of the non-transparent region in the direction parallel to the liquid crystal display panel is greater than or equal to a set distance d. The manufacturing method of the liquid crystal display panel disclosed by the invention comprises the step of calculating the minimum distance d' between the boundary of the channel region and the boundary of the non-transparent region in the direction parallel to the liquid crystal display panel. Through the technical scheme, the TFTs are effectively prevented from being quickly degraded in use, and thus the design and production efficiency of the liquid crystal display panel is promoted. Related products manufactured by utilizing the manufacturing method of the liquid crystal display panel disclosed by the invention are more reasonable in structure and more excellent in product feature.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display, in particular to a liquid crystal panel and a method for manufacturing the liquid crystal panel. Background technique [0002] In flat panel display (FPD) technology, liquid crystal displays (LCD, Liquid Crystal Display) have the advantages of being light, thin, short, and greatly saving placement space. They have gradually replaced cathode ray tube displays and become mainstream displays. Among various types of LCDs, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is a type of active matrix type of liquid crystal display. TFT-LCD has excellent performance and is suitable for large-scale automated production. , And low raw material costs, so it occupies an important position in LCD. [0003] In the TFT-LCD manufacturing process, product design is related to the performance of the final product. The design of the TFT of the liquid crystal panel is the most important thing in the entir...
