description An LED light guide device comprises a light guide plate supporting frame and a light guide plate at least partially located in the light guide plate supporting frame. A containing groove is formed in the light guide plate supporting frame, and an opening communicated with the containing groove is formed in one side of the light guide plate supporting frame; the light guide plate is located in the containing groove. The light guide plate comprises a light guide plate body and a guide part connected with one end of the light guide plate body, the guide part is perpendicular to the light guide plate body, the width of the top of the guide part is the same as that of the light guide plate body, and the width of the bottom of the guide part is smaller than that of the top of the guide part. Therefore, Fresnel loss is reduced, light guide efficiency is improved, luminance is improved, pins of the LED light source do not need to be bent, assembly efficiency is improved, product quality is improved, optical films do
