Problems solved by technology

In the manufacturing process of liquid crystal displays, there are many occasions where static electricity occurs. The highest electrostatic voltage is as high as 2000 volts, and it is easy to break down the insulating layer with a withstand voltage of only about 300 volts; and the ITO conductive layer of the common electrode on the color filter side is Covering the entire surface, the graphics are l

Example Embodiment

[0025] 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.

[0026] like Image 6 As shown, a step layer 18 is provided in the non-data line area coated with the sealant on the array substrate. Through the arrangement of this layer, the gap heights of the liquid crystal cells in the non-data line area and the data line area are different. Generally, the height of the non-data line area is set to be smaller than the height of the data line area, and the difference between the two heights should be much larger than the compression a...

Abstract

The invention discloses a liquid crystal display device, which comprises a color film substrate, an array substrate arranged opposite to the color film substrate, a conducting layer arranged on the color film substrate, an insulation layer arranged on the array substrate, a data line layer arranged in the insulation layer, a section difference layer arranged on the array substrate of a non-date line region, and a frame sealing rubber layer arranged between the array substrate and the color film substrate, wherein a space between the array substrate and the color film substrate is called as the thickness of a liquid crystal box; the region having the data line layer is defined as a data line region; the region without the data line layer is defined as the non-date line region; and a plurality of gold balls are arranged in the frame sealing rubber layer. The liquid crystal display device effectively prevents short circuit of the data line at the frame sealing rubber coating part on the array substrate and a common electrode on the color film substrate caused by the gold balls in the frame sealing rubber, and reduces the occurrence of displaying bad phenomena so as to improve yield and dependency for long-term use of products.

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. Generally, a liquid crystal display (LCD) device has an upper substrate and a lower substrate spaced apart from each other and facing each other. A plurality of electrodes formed on the two substrates face each other. The liquid crystal is sandwiched between the upper and lower substrates. A voltage is applied to the liquid crystal through the electrodes on the substrate, and then the alignment of the liquid crystal molecules is changed according to the applied voltage to display images. Because the liquid crystal display device does not emit light as mentioned above, it needs a light source to display images. Therefore, the liquid crystal...
