Spacer for liquid crystal display and manufacturing method thereof

Abstract

The invention provides a spacer for a liquid crystal display and a manufacturing method of the spacer. The liquid crystal display comprises an array substrate, a color film substrate and the spacer located between the array substrate and the color film substrate, the array substrate and the color film substrate are oppositely arranged, and the spacer is composed of an inorganic material layer and an organic resin layer located on the inorganic material layer. The cross sectional area of the two ends of the spacer is smaller than that of the middle of the spacer. The cross section of the spacer is in the shape of a mushroom with the two ends small and the middle large. According to the spacer, due to the fact that the inorganic material layer is located below the organic resin layer, the spacer with the two ends small and the middle large is formed through the dry etching technology, and therefore the supporting capacity of the spacer is enhanced, and it is guaranteed that the box thickness is stable.

Description

Technical field [0001] The invention belongs to the field of liquid crystal display devices, and in particular relates to a spacer for a liquid crystal display and a manufacturing method thereof. Background technique [0002] At present, the liquid crystal panel has been widely used, and the liquid crystal display is composed of a color filter substrate, an array substrate, and liquid crystal sandwiched between the two substrates. In order to keep the gap between the color filter substrate and the array substrate uniform and constant, a spacer is usually provided between the two substrates. figure 1 It is a schematic diagram of the distribution of spacers on the side of the color filter substrate in the prior art, where R, G, and B respectively represent red, green, and blue barriers, and the red, green, and blue barriers can transmit light as the opening area 20. The distance between the spacer 10 and the opening area 20 is d. When the spacer 10 is closer to the opening area 20,...

AI Technical Summary

Problems solved by technology

The distance between the spacer 10 and the opening area 20 is d. When the spacer 10 is close to the opening area 20, the liquid crystal molecules near the spacer 10 will be poorly oriented, and light leakage will occur around the spacer 10, resulting in poor contrast of the liquid crystal display. Reduced, affecting the display quality of LCD monitors

In order to avoid this situation, the distance d between the spacer 10 and the opening area 20 can only be increased, that is, under the condition that the opening ratio is constant, the area of ​​the lower bottom of the spacer needs to be reduced. Since the existing spacers are all trapezoidal, the reduced The lower bottom area of ​​the spacer will make the spacer thinner, and the support and recovery ability will be reduced, so the thickness of the box cannot be guaranteed
