摘要： A backlight unit of thin-type comprises: at least one or more light source(s); plural numbers of light guide plates, each of which is configured to guide and irradiate the light of the light source(s) to a side of a liquid crystal panel; and a chassis, on which the light source(s) and the light guide plates are fixed, thereby being constructed by aligning the light guide plates, wherein the following conditions are satisfied: 15.0 mm>h, 20°≦θ≦60° when assuming that a distance from an irradiation surface of the backlight unit to the light guide plate is “h”, and that an angle indicative of a half-value light intensity of a light emitting from a light emission surface of the light guide plate, thereby providing a video of high picture quality, and there is also provided a video display apparatus applying the same therein.
