PURPOSE:To decrease the light losses of a liquid crystal panel so as to assure the brightness of a display body and to eliminate crosstalk so as to improve quality by providing a thin-film layer varying in coefft. of thermal expansion from reflection electrodes between a plane substrate and the reflection electrodes. CONSTITUTION:The diffusion reflection plate provided with the reflection electrodes on the plane substrate has the thin-film layer 2 varying in the coefft. of thermal expansion from the reflection electrodes 3 between the plane substrate 1 and the reflection electrodes 3. The reflection electrodes 3 are metallic thin films and are formed to have ruggedness for the purpose of diffusion reflection. The thin-film layer 2 consists preferably of org. matter and the reflection electrodes 3 may serve also as the electrodes for the display body. The production of the diffusion reflection plate is executed by depositing the reflection layer while heating the thin-film layer 2 formed on the plane substrate 1 and etching this reflection layer to form the reflection electrodes 3. The org. thin-film layer is wrinkled by a difference in the coefft. of thermal expansion between the org. thin-film layer and the reflection thin-film layer and the fine ruggedness necessary for diffusion reflection is simultaneously formed when the plane substrate 1 including the org. thin-film layer 2 is heated at this time. |
