摘要： Provided is a display device that can retard the degradation of light-emitting elements even when the display device is used in a high temperature environment. A display device includes a TFT layer, a light-emitting element layer provided with a plurality of light-emitting elements, a heat dissipating layer, an extraction member, and a thermal insulation layer that insulates the light-emitting elements from external heat. The thermal insulation layer is made from a material containing a first resin in which a metal complex compound having an ammonium salt as a ligand is dispersed. The TFT layer is formed between the heat dissipating layer and the light-emitting element layer. The heat dissipating layer overlaps the light-emitting elements. The thermal insulation layer surrounds the heat dissipating layer. The extraction member is formed to overlap the thermal insulation layer. The heat dissipating layer and the thermal insulation layer are in direct contact with the TFT layer.

摘要： Provided is a method for designing a liquid crystal display device including a liquid crystal layer containing a negative liquid crystal material and a pair of vertical alignment films sandwiching the liquid crystal layer. The method includes a step of determining a coefficient depending on the anchoring intensity of the liquid crystal material in the liquid crystal layer by using a material for forming the alignment film and the liquid crystal material, and a step of determining an optical compensation value necessary for the retardation occurring when the pretilt angle of the alignment film is changed in the liquid crystal display device using the material for forming the alignment film and the liquid crystal material based on the determined coefficient and the following Expressions (1) to (3): Re(photo)=Δn×d[√{square root over ((ne2+no2))}×cos{θ−(X−α)}−no]×C (1) Δn=|ne−no| (2) √{square root over ((ne2+no2))}×cos θ=no (3)

摘要： A liquid crystal display includes a pair of substrates, a liquid crystal layer, and an alignment-controlling layer. The liquid crystal layer is disposed between the pair of substrates and includes a liquid crystal material. The alignment-controlling layer, which is formed by polymerization of a polymerizable monomer added to a liquid crystal composition forming the liquid crystal layer so as to be brought into contact with the liquid crystal layer, and controls an alignment of the liquid crystal material to the substrate at a predetermined angle. One substrate of the pair of substrates has an alignment film coated and formed so as to be brought into contact with the alignment-controlling layer, and the other substrate has no alignment film.
