Problems solved by technology

In particular, when the distance P1 between two adjacent stay wires 152 in the stay wire group 150 is very small, or the distance P2 between adjacent sections 152a of a stay wire 152 that is continuously bent (meandering) is very small, they will be adjacent to each other here. An electric field interference occurs between two pull wires 152 or between two adjacent segments 152a, which causes the arrangement of the liquid crystal molecules 132 to be more chaotic, resulting in light leakage
[0006] In particular, the black matrix 160 above the pull wire group 150 can only provide a certain degree of shading effect, and it is difficult to completely prevent the occurrence of light leakage
In addition, even if the liquid crystal display panel 100 is assembled into a liquid crystal display device, the frame or casing (not shown) around the liquid crystal display panel 100 also has a light-shielding effect, but light leakage will still occur due to structural design restrictions or assembly deviations. Affect display quality

Abstract

The invention discloses a display panel, comprising a plurality of stay wire sets, wherein each stay wire set consists of a plurality of stay wires and the multiple stay wires extend along the same linear direction substantially; each stay wire is provided with a first part and a second part which are respectively arranged on opposite sides of sealant, the first part is arranged between the sealant and an active area of the display panel, and the shortest distance of any two adjacent stay wire sections in the first part is greater than that of any two adjacent stay wire sections in the second part. In addition, the shortest distance between any two adjacent stay wire sections in the first part is 15-35mu m. The design of the stay wire group can reduce electric field interference between adjacent stay wires and avoid light leak to improve the display quality.

Description

Technical field [0001] The present invention relates to a display panel, and more particularly to a display panel that reduces light leakage by changing the electric field distribution of the peripheral circuit area. Background technique [0002] In recent years, the maturity of optoelectronic technology and semiconductor manufacturing technology has led to the vigorous development of flat panel displays (FPD). Liquid crystal displays are based on their low-voltage operation, no radiation scattering, light weight, and small size. It has gradually replaced traditional cathode ray tube displays and has become the mainstream of display products in recent years. [0003] figure 1 It is a top view of a known liquid crystal display panel. Such as figure 1 As shown, the liquid crystal display panel 100 has an active area 100a and a peripheral circuit area 100b located at the periphery of the active area 100a. The active area 100a is provided with a pixel structure (not shown) arranged i...
