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： 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： 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.

摘要： In a liquid crystal display device, a first substrate adjacent to a liquid crystal display panel is subjected to rubbing in a first direction that is the same as a polarization axis direction of light emitted from the liquid crystal display panel, and a second substrate that interposes a liquid crystal layer with the first substrate is subjected to rubbing in a second direction at a right angle with the first direction. The second direction is made the same as the polarization axis direction of polarized sunglasses to allow visual recognition of the image using the polarized sunglasses. Electrode patterns formed by alternately providing narrow and wide electrodes are arranged on the upper and lower substrates in a direction at a right angle with each other so that the rubbing directions on the upper and lower substrates form a right angle to ensure stable 3D display.

摘要： An object of the present invention is to realize an image display device for color display with high luminance and high contrast. In the present invention, a unit cell 111 is filled with electrophoresis ink including two kinds of particles different in chargeability and color being dispersed in transmissive solvent 107. Voltage is applied to an opposite electrode 103, a stacked lower electrode 104 and an upper electrode 105 and thereby electrically charged particles 108a and charged particles 108b are moved to a first opening 106a and a second opening 106b where an insulating layer 110 is provided on the lower electrode 104 and the upper electrode 105. Thus assemblage and diffusion state of two kinds of particles are controlled. Thereby, a unit cell 111 obtains four display colors. Since the lower electrode 104 can be made to be a reflecting layer covering the entire unit cell, it is possible to make the aperture ratio large and the reflection percentage large.
