Description

  The present invention relates to a cell gap forming method for a liquid crystal panel, and is particularly applied to the manufacture of a liquid crystal panel. It relates to a method of forming.

  Liquid crystal is a widely used material for display products, and the liquid crystal forms a light passing through non-passing action by applying a voltage to the double-sided electrodes. In general, a known liquid crystal layer has a very thin thickness between two electrodes. For example, in a TFT type liquid crystal display, the thickness is 6 to 8 μm, and a gap between the TN or STN type liquid crystal panel and the liquid crystal layer is 10 μm. It is as follows. The average thickness of the liquid crystal layer of the LCOS micro display is about 3 to 5 μm.

The characteristics of the known relatively thin liquid crystal panel are as follows.
1. 1. Extremely rapid rise and fall reaction time of liquid crystal molecules, relatively thin cell gap and low voltage drive liquid crystal material, lower power consumption achieved by low voltage drive, and electronic control circuit that can be easily designed. 2. A cell gap having a relatively high transmittance and a low thickness can form a relatively high transmittance. Easy to assemble. The relatively thin cell gap is usually maintained uniform by using spacer particles. The cell gap is widely adopted in the liquid crystal display industry. The relatively small gap particles are easy to acquire and seize during the manufacturing process.

  However, depending on the application area, a liquid crystal layer having a relatively large thickness is required, but it poses a driving problem.

  In the production process of a well-known liquid crystal panel, an adhesive is dropped on the inner surface of the glass substrate and a liquid crystal housing portion is formed, and the upper end glass substrate is sealed at the upper end to form an internal liquid crystal housing structure. The liquid crystal is injected into the internal liquid crystal housing structure after being evacuated by a decompressor, or the liquid crystal is injected into the liquid crystal housing structure by another well-known dropping method, and the spacer particles are mixed to form and maintain the cell gap. .

  If the cell gap is increased to 30 μm, 50 μm, 100 μm or higher, it is difficult to obtain spacer particles and the cost is greatly increased. In other words, even if spacer particles with a relatively large particle size can be forcibly solved, the inner liquid crystal housing structure cannot maintain and form a relatively thin adhesive inner wall, and the width is greatly increased to meet the demand for miniaturization. Such a structure is unacceptable in such a manufacturing process situation.

  As a prior art document, for example, there is Patent Document 1, which discloses a well-known typical method of manufacturing a liquid crystal panel, which can only make the spacer distribution uniform and cannot achieve the effect of forming a thick gap.
