面光源装置和液晶显示装置

Abstract

面光源装置和液晶显示装置,在同时使用两种以上的LED光源作为面发光装置的光源时,能够廉价地显示颜色再现范围宽的高品质的图像。面光源装置(500)具有:发出不同颜色的多个光的多个LED(6、7);以及导光体(5),其将多个光混色,并射出混色后的光。导光体(5)具有:被独立地入射多个光的光入射部(11);以及光出射部(8),其设置于光入射部(11)的侧方,通过改变从光入射部(11)入射且在导光体(5)内传播并进行混色的多个光的传播角度,控制从导光体(5)出射的光的光出射量和光出射位置。
Disclosed are a surface light source device and a liquid crystal display device. When more than two LED light sources are simultaneously taken as light soruces of a surface light source device, a high-quality image having the wide color reproduction range can be cheaply displayed. The surface light source device (50) includes a plurality of LEDs (6, 7) for emitting a plurality of light having different colors, and a light guide body (5) for mixing the colors of the plurality of light and emitting light having colors mixed. The light guide body (5) includes a light incident portion (11) for causing the plurality of light to be individually incident, and a light emitting portion (8) provided beside the light incident portion (11) and changing propagation angles of the plurality of light which is incident from the light incident portion (11) and propagated into the light guide body (5) to mix colors, thereby controlling a quantity of light emission from the light guide body (5) and a light emitting position.
