Abstract

PURPOSE:To reduce a voltage loss by forming conductive color filters in a liquid crystal panel and uniting an electrode and the color filters together in one body. CONSTITUTION:The electrode 2 is formed on a transparent electrode 1 and a compound obtained by mxing tin oxide powder and anthraquinone pigment with epoxy resin is used to form conductive color filtes 7 of red, blue, and green, which are united with the electrode 3. A liquid crystal layer 6 is charged between this substrate 1 and a substrate 2 provided with the electrode 4. When a voltage is applied between the electrodes 3 and 4, the voltage is applied to the liquid crystal layer 6 directly, so the voltage loss is small.
