Abstract

PURPOSE:To enable reduction of injection time of liquid crystals by injecting the liquid crystals through one side, sealed in dots, of the frame-shaped sealing layers for bonding a liquid crystal cell. CONSTITUTION:Frame-shaped linear sealing layers 3 are formed on the sides of both of upper and lower bases 1, 2 each provided with a transparent electrode. Since one of the sealing layers 3 is formed into a layer 11 sealed in dots, and there are spaces between the dots of the sealing material, all the length of the one side is used for the inlet of liquid crystals, thus promoting their injection. The layer 11 also contributes in fixing both bases 1, 2 at a prescribed interval. The layer 11 having passed the liquid crystals is sealed with a sealing agent made of an epoxy resin and an L- or U-shaped film. These film enhances the sealing and bonding forces of the layer 11 and improves the humidity resistance characteristic of the sealing agent.

In conventional liquid crystal display panels manufactured using this method,
We manufacture liquid crystal display panels for large-screen displays with an increased amount of information, and develop electrode substrates to improve the characteristics of the currently widely used TN type liquid crystal display panels to achieve a wide range of high contrast. When injecting liquid crystal material into a large liquid crystal cell with a narrow electrode substrate spacing, such as in the production of liquid crystal display panels with small spacing, the resistance of the injection hole to the inflow of liquid crystal material is large, and the injection process takes a significant amount of time. Such problems arose.
