BACKLIGHT UNIT AND VIDEO DISPLAY DEVICE UTILIZING SAME
摘要
<p>Provided is a backlight unit that exhibits a spatially uniform luminance distribution through reduction of non-uniform luminance. The present invention is a backlight unit (7) that includes LEDs (2) and a light guide plate (1) for guiding light from the LEDs toward a liquid crystal panel, wherein concave sections (11) are provided on the back side of the light guide plate (1), and the multiple LEDs (2) are housed inside the concave sections (11). Additionally, light quantity restriction members (6) are provided on the light exit plane side of the light guide plate (1) at positions facing the concave sections (11). Each of the light quantity adjustment members is characteristic in that the light transmittance increases with the distance away from the position corresponding to the LED (2).</p>
