Title: Double current contraction type light emiting diode
Inventor: TAKAGI JIYUNKOU
IPC: H01S5/00
Filed: 1979-06-27
Abstract: PURPOSE:To eliminate the nonlinearity caused by a single current enclosure structure in a double current contraction type light emitting diode by forming a current contraction portion for limiting a light emitting region in the upper and the lower directions of the light emitting layer. CONSTITUTION:Upper and lower current contraction diameters dw and de are formed equal. An electric current implanted to the upper current contraction portion 39 from a P-type side electrode 36 flows as it is toward an opposite electrode 40 directly thereunder, and even if the input current level is altered, no current path changes, and the light emitting diameter d does not accordingly vary. When the layer resistance of the P<+>-type diffused layer of the upper current contraction portion 39 is further formed sufficiently low, the current density in the light emitting region d becomes constant. Accordingly, the current density distribution does not become in disorder due to the variations in the input current level.

Filed: 1993-04-09
Abstract: PURPOSE:To enable the execution of a high-brightness display and a high- contrast display by the effect of a diffraction grating, etc., by using a high- polymer dispersed liquid crystal. CONSTITUTION:Pixel electrodes of the liquid crystal panel are constituted of a light transmittable conductive material, etc., and a reflection electrode 23 is formed on a counter substrate 21. The pixel electrodes 24 are constituted by lamination of dielectric thin films having l/4 (l is a main design wavelength) optical film thickness and ITO films of l/2. The light reflected at the boundaries of the pixel electrodes 24 is prevented by the lamination constitution. The diffraction grating consisting of a rugged sectional shape is formed on the reflection electrode 23. The high-polymer dispersed liquid crystal is used for the liquid crystal 26. A refractive index difference arises between the diffraction grating and the liquid crystal and incident light is diffracted when a voltage is not impressed to the liquid crystal layer. The refractive index of the liquid crystal changes to eliminate the refractive index difference between the diffraction grating and the liquid crystal display and the incident light advances rectilinearly when the voltage is impressed.
