Abstract: A liquid crystal display device including an alignment film which has been optically aligned is configured that the liquid crystal has negative dielectric anisotropy, an absolute value of which is equal to or smaller than 5. The alignment film is subjected to an optical alignment process to exhibit the optical alignment property, and includes a first film located at a side in contact with the liquid crystal, and a second film below the first film, which is not optically aligned to have no alignment property. The alignment film is formed by applying a mixture of a first material for forming the first film and a second material for forming the second film to the substrate. The first material for the alignment film accounts for 10 wt. % or more and less than 40 wt. % of a total weight of the first and the second materials.

Abstract: In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

Abstract: According to an aspect, a stretchable device includes: a stretchable substrate comprising bodies and hinges that couple the bodies to each other; and a pair of stretchable resins with the stretchable substrate interposed therebetween. The stretchable device includes a detection region in which a load is capable of being detected and a non-detection region when viewed in a stacking direction in which the stretchable substrate and the stretchable resins overlap. One or more of the hinges are detection hinges each provided with a strain gauge. All of the detection hinges overlap the detection region when viewed in the stacking direction. The stretchable resins each includes: a bonded region that overlaps the non-detection region when viewed in the stacking direction and is bonded to the stretchable substrate; and an unbonded region that overlaps the detection region when viewed in the stacking direction and is not bonded to the stretchable substrate.
