REFLECTION TYPE LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE:To obtain the device which is bright and is wide in visual angle characteristic by using a mirror surface reflecting plate in the twisted nematic liquid crystal display device in which the front substrate is constituted by an optical fiber aggregate plate. CONSTITUTION:In the reflection type liquid crystal display device formed by sandwiching a nematic liquid crystal layer 7 between the optical fiber aggregate plate 4 provided with a liquid crystal molecule orientation layer 6 and transparent electrode 5 and the back glass substrate 11 provided with a liquid crystal molecule orientation layer 9 and transparent electrode 10 and disposing a front polarizer 3 to the top side thereof (observation side) and a back polarizer 12 and reflecting plate 13 to the bottom side thereof, a mirror surface reflecting plate is used as the above- mentioned reflecting plate 13. Hence, the incident angle theta4 of incident angle 15 and the reflection angle theta5 of reflected light 16 become equal and the external light entering through the optical fiber aggregate plate 4 is surely led to the outside through the plate 4.
