Abstract: According to one embodiment, an illuminating device includes a lightguide plate including a curved emitting surface, and an incidence surface including a side edge curved along the emitting surface, a printed circuit board facing the incidence surface, and light sources mounted on the printed circuit board. Each light source includes a light-emitting center, a pair of connection terminals, and a central axis extending through the connection terminals and the light-emitting center. The light sources are arranged along a curved mounting line extending along the curved side edge of the incidence surface on the printed circuit board. The light-emitting centers are located on the mounting line, and the central axes are parallel to each other.

Abstract: A display device includes a side light type backlight for white color display by single color LEDs, an LED set is placed in a concave portion of a light guide plate, in which a first color LED is located in the center and a second or third color LED is located on the side of the first color LED. An incident slit with an arc shaped convex portion is formed facing the first color LED, and a saw tooth slit with a right-angled triangular concave portion is formed facing the second or third color LED. This allows directing the distribution axes of the lights from the second and third color LEDs to the center side, and adjusting orientation angles to allow effective mixing of the three color lights, in order to increase the white color area and effective display area.
Abstract translation: 显示装置包括通过单色LED进行白色显示的侧光型背光源,LED组置于其中第一颜色LED位于中央的导光板的凹部中,第二或第三颜色 LED位于第一色LED的一侧。 形成有与圆形凸部相对的入射狭缝,面向第一颜色LED,并且形成有与第二或第三颜色LED相对的具有直角三角形凹部的锯齿狭缝。 这允许将来自第二和第三颜色LED的光的分布轴指向中心侧,并且调整取向角以允许三色光的有效混合,以便增加白色区域和有效显示区域。
