Abstract
PURPOSE:To obtain a light shielding film which has a high degree of light shielding, forbids the short-circuiting between substrates and has no electrical conductivity by using a TixOy pigment. CONSTITUTION:The light shielding film contains the TixOy (where x/y is larger than 1/2) pigment and is formed by using the ink prepd. by mixing an adhesive agent with the TixOy pigment. The reflection color of the film changes to white - dark blue - purple - black colors as x/y is nearer 1. The degree of light shielding as the dark color systems is thus increased and the thin light shielding film 4 is obtd. However, the volume resistivity of the TixOy pigment decreases as the ratio x/y of x and y of the pigment approaches 1 from 1/2 and, therefore, the danger of the short circuiting is lowered by maintaining the specific volume resistivity thereof at >=10<4>OMEGA.cm. Since the light shielding film 4 having a low transmittance is thereby easily formed, the high contrast is easily obtd. and the problem of injection of a liquid crystal 6 to a narrow spacing is prevented.
