Inventor: GUN YON YAN
IPC: G11B7/1353
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To exactly align an LD and a hologram element by aligning this hologram element in such a manner that the light emitting point of the LD is image-formed at the center of many projected light emitting points.

Title: Display element
Inventor: CHINO EIJI
IPC: G02F1/1333
Filed: 1991-12-25
Abstract: PURPOSE:To obtain the display element which abruptly varies in transmissivity by voltage application and has a good contrast by using thermoplastic resin, thermosetting resin, or polymer liquid crystal for a matrix and orienting it together with liquid crystal. CONSTITUTION:Macromolecules 4 are oriented along the liquid crystal 5 and shows nearly the same refractive index anisotropy (about 1.7 refractive index in visual field direction) with the liquid crystal 5. Consequently, the difference in refractive index in the visual field direction between the liquid crystal 5 and macromolecules 4 is eliminated when no electric field is applied and the liquid crystal becomes transparent. When an electric field is applied, the macromolecule part stays as it is and only the liquid crystal 5 is vertically oriented, so although the refractive index of the macromolecule part is still the refractive index (about 1.7) in a horizontal orientation state, the refractive index of the liquid crystal part varies to a refractive index (about 1.5) in the vertical orientation state. Consequently, the difference in refractive index between the macromolecule part and liquid crystal part becomes about 0.2, thereby obtaining scattering intensity which is nearly twice as large as usual.
