Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0022] Specifically, in the present invention, a certain area of ​​material with a negative thermal expansion coefficient is set in the area from the surrounding edge of the display area to the inner side of the sealant, and the volume expansion coefficient of the material satisfies the condition: β≤-27β 液晶 . When the external temperature becomes low, the volume of the material expands, which can repair the defects such as low-temperature bubbles caused by the small amou...

Abstract

The invention discloses a liquid crystal display device, which comprises an array substrate and a color film substrate opposite to each other, wherein frame sealing glue is coated on the array substrate or the color film substrate, a display area is arranged within a frame sealing glue area, and an area between the peripheral edge of the display area and the inner side of the frame sealing glue is provided with a negative thermal expansion material. The liquid crystal display device disclosed by the invention solves the problems that low-temperature air bubbles are generated within the display area of a liquid crystal panel at a low temperature, and high-temperature vertical flows are generated at a high temperature.

Description

technical field [0001] The invention relates to a display device, in particular to a liquid crystal display device. Background technique [0002] Traditional CRT monitors rely on cathode ray tubes to emit electrons and strike phosphors on the screen to display images, but liquid crystal displays work on a completely different principle. Liquid Crystal Display (LCD) is the first product developed and commercialized in Flat Panel Display (FPD, Flat Panel Display). figure 1 The upper and lower cross-sectional structures of a certain part of the display are given, from top to bottom are the upper polarizer, the color filter substrate, the electrodes, the liquid crystal layer, the array substrate and the lower polarizer. There is a certain distance between the color filter substrate and the array substrate, and a plurality of electrodes on the two substrates face each other. The liquid crystal is sandwiched between two substrates, the voltage is applied to the liquid crystal th...
