摘要： An aspect of the present invention provides a compact light guide device and a light guide apparatus having high productivity and an even light emission property. A light guide device is made of a translucent material, and LED is disposed in a notch step portion formed by cutting at least a part of an inner peripheral surface, thereby guiding light from LED to emit the light to the outside. Particularly, in a surface and a backside of a sidewall portion of the notch step portion, the sidewall portion facing a light-emitting portion of the light-emitting element, at least an inward surface constitutes a reflecting surface diffusing the light, and a pair of facing surface adjacent to each other on both sides of the sidewall portion constitutes a light acceptance surface receiving the light reflected from the reflecting surface.

摘要： A display device has a light guide plate formed with a display pattern by a plurality of diffusion dots having translucency in a display pattern formed region, a light shielding layer, and a light source. A plurality of the light guide plates are arranged facing each other, and the light shielding layer is sandwiched between the light guide plates. Light from the light source is selectively introduced to one of the light guide plates to display the display pattern of the light guide plate. The light shielding layer has a surface facing an observer's side formed by a low reflectivity material and a surface facing a side opposite to the observer's side formed by a high reflectivity material. A region facing the display pattern of the light guide plate positioned on the side opposite to the observer's side than the light shielding layer is cut out.
摘要翻译：显示装置具有通过在显示图案形成区域中具有半透明度的多个扩散点，遮光层和光源形成有显示图案的导光板。多个导光板彼此相对布置，并且遮光层夹在导光板之间。来自光源的光被选择性地引入到一个导光板以显示导光板的显示图案。遮光层具有由低反射率材料形成的面向观察者侧的表面和与由高反射率材料形成的与观察者侧相反的一侧的表面。切割面对位于与遮光层相对的观察者侧的一侧的导光板的显示图案的区域。
