Beschreibung
Zusammenfassung:	The electronic book comprises a display screen, an upper cover plate, a light guide assembly and a light refraction part, the light guide assembly comprises a light guide plate and a light source, the light refraction part is of a three-layer colloid structure and comprises a first colloid layer, a second colloid layer and a third colloid layer which are sequentially arranged from top to bottom, the first colloid layer is attached to the lower bottom face of the upper cover plate, and the second colloid layer is attached to the lower bottom face of the lower cover plate. The third colloid layer covers the upper surface of the light guide plate, and the second colloid layer is connected with the first colloid layer and the third colloid layer. The light refractive index of the first colloid layer is larger than that of the second colloid layer, the light refractive index of the second colloid layer is larger than that of the third colloid layer, the light refractive index of the third colloid layer is larger t
