摘要： Provided is an illuminating device (1) including: a light source (10); a light-guide-plate (20) received light from the light source at a side surface of the light-guide-plate and outputting from a front surface of the light-guide-plate; and reflector (30) disposed on a rear surface side of the light-guide-plate. The light-guide-plate outputs light having a peak of a luminance at an output angle inclined with respect to a normal line of the front surface. A part of the light output at the angle is made obliquely incident on the front surface at an angle smaller than a critical angle to be reflected in the light-guide-plate and, then, when the part of the light obliquely travels to the rear surface and to return to the front surface, polarized light components are converted so as to contain more p-polarized light components than s-polarized, and the part of the light is output.

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 light-guiding member is provided with two light source groups on its both terminals and the light-guiding board comprises two light mixing areas which have a cross section form which is symmetry for its center line, and a light outputting area between these. The light mixing areas function as an area in which the lights from each adjacent light source group are mixed and at the same time function as an area to output the mixed lights from each remote light source group. The light outputting area functions as an area to pass a part of the mixed lights from the two light source groups and at the same time functions as an area to output the rest.
