Abstract

PURPOSE: To enhance the reliability of liquid crystal display element by reducing the quantity of Na accumulated in the insulator layer surface, by removing the surface until the concentration of Na becomes sufficiently low after heating the insulator surface composed on a glass substrate.
CONSTITUTION: SiO2 layer are provided on two glass substrates having transparent electrodes, and fritglass is screen-printed to the sealing part, then a primary heating is given, for instance at 480°C for 1 hour. With the transparent electrode sides in opposed configuration, the two glass substrates are given a secondary heating, for instance at 500°C for 1 hour to form a sealing. Etching liquid, such as HF solution, is poured into this cell, and the surface of SiO2 layer is removed by about 100 Å. After washing in water and drying the cell, vertical orientation processing liquid is poured into the cell to treat the substrate surface with vertical orientation. Then, liquid crystal is poured in, and the pour hole is sealed.
