<p>PURPOSE:To obtain a liquid crystal display element of positive display having an inclined vertical orientation by overcoating inorganic insulation layers on the electrode surface constituting the element and subjecting the same to directing treatment and further applying a specific orientation surface treatment. CONSTITUTION:Insulation layers 13, 17 of inorg. materials such as ZrO2 are overcoated on an electrode plate consisting in forming predetermined pattern electrodes 12, 18 on glasses 11, 19, etc. A directing treatment of a nonvacuum system such as rubbing is applied thereon. Further, the surface treatment by vertical orienting agents 14, 16 of an org. silane system shown by R-SiX3 (R is alkyl groups of C16-20, etc., X is halogen or alkoxy groups) is applied to obtain the desired inclined orientation angle combined with the insulation layers 13, 17. A pair of these electrode plates are opposedly disposed and the periphery is sealed by means of a sealing material 15, thence a nematic liquid crystal 20 or the like added with a dichromatic dye is injected between the electrode plates.</p> |
