Title:
LIQUID CRYSTAL ELECTROOPTICAL DEVICE
Document Type and Number:
Japanese Patent JPH052187
Kind Code:
A
Abstract:
PURPOSE:To provide the liquid crystal panel which has less stray light and enables display of a high contrast to be conducted by providing a layer for absorbing the light from a light source in at least a part of the side periphery of a metallic wiring. CONSTITUTION:A layer 109 which absorbs the light is provided in a part of the side periphery of the metallic wiring 104 of the active element on at least one substrate of the substrates constituting the liquid crystal panel. While the metallic wiring 104 is provided directly on the substrate in such a case, films having other functions are provided on top and bottom of this wiring 104 at need. The light absorption layer 109 does not generate the stray light and has rather a function to decrease the stray light. The materials to be used can absorb the light as far as the materials are black. Thin films essentially consisting of the carbon formed by a vapor phase method (for example, diamond-like carbon, amorphous carbon), black org. material films, oxide films of metals, etc., are applied to the above-mentioned materials.
