PURPOSE: To provide a bright liquid crystal display device with high diffusibility, a low drive voltage, a high contrast ratio and with an excellent gradational property by providing an electrode pattern forming oblique electric field at least in the four directions. CONSTITUTION: A transparent upper electrode 13 of a checkered pattern is formed on one surface of an upper substrate 11, and a transparent lower electrode 14 is formed on one surface opposing to each other of a lower substrate 12. The upper electrode 13 is constituted so that a conductive body unit 13a1 of which a transparent conductive body part 13a is a nearly square is connected at respective corner parts conductively to be integrated, and it forms them pattern surrounding a non-conductive body part 13b between the conductive body parts. The lower electrode 14 is formed to the checkered pattern between the transparent conductive body parts 14a and the non-conductive body parts 14b. The upper electrode pattern is symmetrical with the lower electrode pattern, and when a voltage is applied between both electrodes 13, 14 by a power source 30, the oblique electric field being the electric field having an electric field component parallel to a substrate surface in addition to the electric field in the normal direction of substrate is formed in a liquid crystal layer 17. |
