Abstract: A light-diffusion member (7) includes: a substrate (39) having light-transmitting properties; a light-diffusion portion (40) on a face of the substrate (39) facing a display medium (6); and a light-blocking layer (41) on a part of the face of the substrate (39) facing the display medium (6) other than where the light-diffusion portion (40) is provided. The light-diffusion portion (40) includes: a light-emitting end face (40a) in contact with the substrate (39); and a light-incident end face (40b) facing, and being larger in area than, the light-emitting end face (40a). The adhesive layer (42) adheres to light-incident end face (40a) and partly (42a) encroaches into a space (43) between the light-diffusion portion (40) and light-blocking layer (41).

Abstract: A composition containing a photosensitive polymer in which the molecular structure changes due to absorption of light or a precursor of the photosensitive polymer and an additive that absorbs at least ultraviolet rays and that provides the energy of the absorbed ultraviolet rays to the photosensitive polymer, wherein the photosensitive polymer absorbs at least some of the ultraviolet rays when specifically polarized ultraviolet rays are irradiated as the light so as to undergo a first reaction that generates anisotropy in the molecular alignment of the photosensitive polymer in accordance with the polarization direction of the polarized light and a second reaction that further enhances the anisotropy generated in the molecular alignment of the photosensitive polymer by the first reaction, and the additive absorbs the irradiated ultraviolet rays so as to convert the ultraviolet rays to energy for causing the second reaction and provide the resulting energy to the photosensitive polymer.

Abstract: The present invention makes it possible to reduce an afterimage phenomenon while preventing an increase in driving voltage. A liquid crystal display device (10) includes: a liquid crystal layer (3) and a pair of substrates which face each other across the liquid crystal layer (3); and an upper electrode (4), a lower electrode (5), and a first insulating layer (6) which are provided in a stack on one substrate (1) of the pair of substrates so that the upper electrode (4) and the lower electrode (5) overlap each other via the first insulating layer (6), the upper layer electrode (4) having an end surface which constitutes an opening of the upper electrode (4), the end surface being forward tapered and forming, with the one substrate (1), an average angle of inclination of not more than 30 degrees.
