摘要： PROBLEM TO BE SOLVED: To secure the high quality of a display picture even under the environment of brightness exceeding the high-quality picture display limit of a conventional screen.
SOLUTION: The screen 20 for the front projection display is provided with a reflection layer 1 having a reflection surface 1A bent in a saw-toothed state; a transparent smoothing layer 2 brought into close contact with the saw-toothed reflection surface of the reflection layer; a light control layer 3 brought into close contact with the surface on the counter reflection layer side of the smoothing layer to transmit the light while scattering it or while making it advance straight depending on the incident direction of the light; or furthermore an antireflection layer 4 brought into close contact with the surface on the counter smoothing layer side of the light control layer and restraining the reflection from the surface.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device in which the splay-bend transition of the liquid crystal layer takes place surely at a high speed at a regular driving voltage and it is less to be constrained on the constutional material or on the production process is added.
SOLUTION: The liquid crystal layer 2 has a first region 11 in which an orientation direction of a liquid crystal molecule 1 determined by alignment controllability of an alignment layer in contact therewith exists in a first direction 21, a second region 12 in which the orientation direction exists in a second direction 22 turning to the right with >0° and 0° and

摘要： PROBLEM TO BE SOLVED: To provide a three-dimensional display having further improved visibility and easy controlling properties in a three-dimensional display using a back light whose light direction is controlled by time-sharing. SOLUTION: The three-dimensional display is composed of a main part and additional elements provided in the main part. The main part has a stripe light source 3 in which first and second light emitting parts 31, 32 (the first and second emitting parts correspond to the left and right eyes, respectively, ) are alternately arranged in stripes; lenticular lenses 4 to direct the light emitted from the first and second light emitting parts to a first and second directions, respectively; a transmission type LCD 5 the back face of which is illuminated with the light emitted from the lenses; and a three-dimensional display controller 6 which alternately turns on the first and second light emitting parts at an invisible rate to alternately display, on the transmission LCD, first and second parallax images synchronized with the above blinks and corresponding to the first and second directions. The additional elements are an antireflection film 7 to prevent reflection on the image display screen; a blink mode switch 8 to act on the three-dimensional display controller to simultaneously and continuously turn on the first and second light emitting parts; and/or a stripe pitch controller 9 to move the boundary between the first and second light emitting parts.
