摘要： Provided is a liquid crystal display device with a backlight including a light guide plate. The light guide plate includes, a reflective polarizing plate for transmitting a P-polarized component and reflecting an S-polarized component, a reflector for reflecting the S-polarized component reflected by the reflective polarizing plate, and a polarization converting member for converting the S-polarized component to a P-polarized component. The reflective polarizing plate and the reflector are tilted at an angle such that reflecting surfaces thereof are not perpendicular to four sides of the liquid crystal display panel and are disposed such that the S-polarized component contained in a main component of light emitted from the light sources is reflected by the reflector. This keeps small the size of the liquid crystal display device and still improves reuse efficiency of the light emitted from the light sources.

The anisotropic diffusion sheet includes a refractive index anisotropic diffusion sheet stretched in an absorption axis direction in which a concave-convex portion is formed on a surface of the reflective polarized plate, and an isotropic material part laminated on a surface of the concave-convex part. The isotropic material part has an isotropic reflective index.

摘要： A planar light emitting element is capable of outputting light having high directivity in at least one direction. The planar light emitting element has a light guide plate and first and second low refractive index layers. Light incident on the light guide plate is totally reflected on the interface between the light guide plate and the second low refractive index layer, propagates in the light guide plate, and is output from the light guide plate to the first low refractive index layer through a light output opening section. When a refractive index of the first low refractive index layer is sufficiently smaller than a refractive index of the light guide plate, the light propagates in the light guide plate at a large angle with respect to a light output surface of the light guide plate. When the difference between the refractive indexes of the first and second low refractive index layers is small, a spreading angle of light output to the first low refractive index layer is small. The light having high directivity is reflected on a reflective mirror and output from the planar light emitting element.

摘要： A liquid crystal display device includes light source sections 150, a light guide plate 130 guiding light of the light source sections from a side edge and including a light emitting surface, and a liquid crystal panel 200 including a lower polarizer 230 opposed to the light emitting surface. The lower polarizer has a transmission axis generally along a light guide azimuth in which the light guide plate guides the light. The light guide plate includes a polarization converting section 131 on at least one of the light emitting surface and a rear surface. The polarization converting section reflects light made incident from the light guide azimuth in a different traveling azimuth and further reflects the light reflected in the different traveling azimuth to bring the traveling azimuth closer to the light guide azimuth to thereby convert polarization of the light traveling from the light guide azimuth.

摘要： An illuminating device includes: a light source; a light guide plate which converts light emitted from the light source into a surface light ray and emits the surface light ray through a front surface of the light guide plate; and an optical sheet which changes a propagation direction of the surface light ray emitted from the light guide plate. The light source is arranged in end surface different from the front surface in the light guide plate. A polarization state converting structure to convert a polarization state of the light propagating through the light guide plate is provided in a surface opposing the front surface in the light guide plate. The polarization state converting structure contains an inclination plane having a ridge line in a direction different from a direction in parallel to the longitudinal direction of the end surface.
