Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPH05142564
Kind Code:
A
Abstract:
PURPOSE:To display an image of a high contrast by improving a light shielding property from an external light to an optical switching element. CONSTITUTION:On a fiber plate 11a, plural linear light emission sources are arrayed along the Y direction, and plural linear electrodes are arrayed in the X direction so as to intersect on them. On the fiber plate 11a, an electrode 12 combined with a role as a light shielding layer for preventing an external light from the lower part of an element from being made incident on an optical switch element 18 formed in the upper part is formed, and in addition to the electrode 12, the lower insulating layer 13, a light emitting layer 14, the upper insulating layer 15, an electrode 16 and a picture element electrode 17 are formed. In an intersection part of the linear light emission source and the linear electrode, the optical switch element 18 is provided between the linear electrode and the picture element electrode 17. On a transparent electrode 21 provided on the other fiber plate 11b, a light shielding layer 22 is formed in accordance with a pattern of the optical switch element 18. In such a way, a liquid crystal layer 24 is formed between substrates formed with each layer.
