摘要： An illumination apparatus is disclosed. The illumination apparatus includes a polarization plate, a light source, and a light transmission film disposed between the polarization plate and the light source and including a plurality of prisms formed on a surface thereof. The plurality of prisms each have a ridge line in a first direction and are continuously arranged in a second direction perpendicular to the first direction. The light transmission film is disposed such that a ridge line direction of the plurality of prisms is one of a perpendicular direction and an approximately perpendicular direction to a transmission axis of the polarization plate. The plurality of prisms each have refractive indexes in the ridge line direction, an arrangement direction, and a thickness direction, the refractive index in the ridge line direction being larger than the refractive indexes in the arrangement direction and thickness direction.

摘要： A surface-emitting semiconductor laser (VCSEL) having a structure in which the single horizontal mode of high power is stably maintained, and an optical device including a light-source device having this surface-emitting semiconductor laser are provided. A scattering-loss-structure portion composed of a low refractive-index region is disposed around a main current path in a surface-emitting semiconductor laser, namely around a cavity structure portion; the low refractive-index region is disposed at intervals; and the shape of the tip portion opposing to the center portion is set to be a tapered shape, for example, at an acute angle.

摘要： A phase difference element, in which imbalance hardly occurs between right and left pictures during displaying a three-dimensional image, and a display device having the phase difference element are provided. A base film 31 of the phase difference element 30 includes, for example, a thin resin film having optical anisotropy. A slow axis AX3 of the base film 31 points in a vertical or horizontal direction, and points in a direction intersecting with a slow axis AX1 of a right-eye region 32A of the phase difference element 30 and with a slow axis AX2 of a left-eye region 32B thereof. Thus, influence due to optical anisotropy of the base film 31 is exerted on each light being transmitted by the base film 31, so that the influence is not extremely greatly exerted on only one of light corresponding to a right eye and light corresponding to a left eye, the respective light being transmitted by the base film 31.
