Title:
MATRIX LIQUID CRYSTAL PANEL
Document Type and Number:
Japanese Patent JPH06118403
Kind Code:
A
Abstract:

PURPOSE: To obtain a liquid crystal panel having no short defect in the electrode of upper and lower substrate and having reduced afterimage by prescribing the kind of the oriented film which is used to orient the liquid crystal and the film thickness of the liquid crystal material and the oriented film.

CONSTITUTION: On the surface of the electrode for liquid crystal driving 18 which is on at least one side of the substrate 14 of the liquid crystal panel holding a liquid crystal layer 11 in between the couple of substrate 14, 15 having the electrode for liquid crystal driving 18, 19, polyimide 12 as the org. film having ≥1500 (angstrom) film thickness is formed, and the org. film 12 is used as an oriented film. In this case, on the surface of the electrode for liquid crystal driving 18, 19 which is on the couple of the substrate 14, 15, the insulated thin film except the org. film 12 or the oriented film having more than 1500 film thickness in not formed. And, the film hardness of the org. film 12 is more than (H) on pencil hardness, and the liquid crystal material 11 to be used is fluorinated liquid crystal, the polyimides 12, 13 to be used for both two substrates 14, 15 are composed of the material having very small polarity.
