Title:
透明ディスプレイ
Document Type and Number:
Japanese Patent JP6313568
Kind Code:
B2
Abstract:
The present invention provides a transparent display comprising a light source (170); a first liquid crystal layer (140) for transmitting a first part of the light emitted from the light source having a first polarisation state and reflecting a second part of the light emitted from the light source having a second polarisation state; a light-transmissive image display device including a second liquid crystal layer (130) arranged so that the second part of the light is incident on the second liquid crystal layer (130); wherein when the light-transmissive image display device is in a first state, the second part of the light is transmitted through the second liquid crystal layer (130); and when the light-transmissive image display device is in a second state, the second part of the light is reflected by the second liquid crystal layer (130), so that an image can be generated in the first state and the light-transmissive image display device appers transmissive in the second state. Since the transparent display can realize the function of a transparent display without the use of a sheet polarizer or a light guide plate, the light transmittance can be improved.
