    摘要： Provided is a top emission type organic light-emitting display device having the emission luminance thereof improved by increasing a quantity of electrons injected into an electron injection layer. At least a cathode, an electron injection layer, an electron transport layer, a light-emitting layer, a hole transport layer, and an anode are sequentially accumulated on an insulating substrate. The electron injection layer is formed with a co-deposited layer having both tris(8-hydroxyquinoline)aluminum (Alq3) and lithium (Li) evaporated thereon. The electron transport layer is formed with a deposited layer having tris (8-hydroxyquinoline)aluminum (Alq3) evaporated thereon. The ratio of Li to Alq3 in the co-deposited layer is equal to or larger than 1 and equal to or smaller than 3. The thickness of the co-deposited layer is equal to or larger than 1 nm and equal to or smaller than 3 nm. The thickness of the Alq3-deposited layer is equal to or larger than 5 nm and equal to or smaller than 7.5 nm. Consequently, a quantity of resistive components decreases, a current increases, and a quantity of electrons injected into the light-emitting layer increases (the electron mobility gets larger). Eventually, the emission luminance improves.

    摘要： Light-emitting devices and light-emitting displays for realizing bright display by allowing light emitted from an emissive layer to efficiently contribute to a display. Polarization separators are arranged between the emissive layer and a phase plate. In the light of a wavelength range which includes a part or all of a light-emission wavelength range of the emissive layer and is narrower than a visible wavelength range and is directed from the emissive layer side to the polarization separators side, the polarization separators reflect circularly polarized light components which are converted into linearly polarized light that is absorbed by the polarizer due to the operation of the phase plate and transmit the other light.

    摘要： In a liquid crystal display device capable of realizing a viewing angle equivalent to the Braun tube and for controlling display with an electric field in parallel with a substrate surface, a liquid crystal display device is provided which is less in unevenness of display and homogeneous in luminance. A liquid crystal display device has a pair of transparent substrates arranged oppositely through a liquid crystal, means for regulating a direction of initial alignment of the liquid crystal, and a pixel electrode and a counter electrode formed spaced from each other in each pixel region on a liquid crystal side surface of the transparent substrate, wherein an electric field is given between the pixel electrode and the counter electrode to thereby control an amount of light transmitting in the crystal liquid between the electrodes. A light transmissive region in the pixel region has, with respect to one region set with an angle given by an electric field direction and an initial alignment direction between the pixel electrode and the counter electrode, another region having an electric field direction and an initial alignment direction that are different in the angle.
