Problems solved by technology

The place of production needs to ensure that the sealant area and the liquid crystal area have the same thickness, but during use, due to the temperature change of the use environment, the sealant area and the liquid crystal area will have different degrees of expansion and contraction changes, which will cause the edge area of ​​​​the LCD display to be damaged. Inconsistent with the thickness of the middle area, and eventually lead to light and dark stripes on the edge of the display, seriously affecting the display effect

Abstract

The application provides a liquid crystal display panel comprising a first substrate, a second substrate arranged opposite to the first substrate, a gap filling layer arranged between the first substrate and the second substrate, and a backlight module. A color resistance layer is arranged on a second substrate in a non-display area, so that the edge area and the middle area of the liquid crystaldisplay panel have the same expansion and shrinkage states in different cold and hot environments, the situation that the thickness of the edge area and the thickness of the middle area are inconsistent is prevented, light and shade stripes caused by inconsistency are eliminated. Compared with the prior art, the image quality of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display panel. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) is one of the most widely used display devices at present. With the development of thin film transistor liquid crystal display technology, the requirements for the picture quality of the display are increasingly higher. The liquid crystal display is composed of oppositely arranged two-sided substrates and liquid crystal filled between the substrates. A sealant is provided outside the liquid crystal layer to seal the liquid crystal and bond the two-sided substrates. The place of production needs to ensure that the sealant area and the liquid crystal area have the same thickness, but during use, due to the temperature change of the use environment, the sealant area and the liquid crystal area will have different degrees of expansion and contraction changes...
