| description | The invention relates to a thinning light guiding structure which comprises an incident light source, a light incident side optical coupling structure and a light guiding structure body. The light guiding structure body comprises a light guiding plate. The light incident side optical coupling structure comprises an upper chamfer and a lower chamfer arranged at the front end of the light guiding plate. An included formed between the upper chamfer and the lower chamfer is alpha. An included angle formed between the lower chamfer and an extension line on the lower surface of the light guiding plate is beta. A line is connected between a lower end point of the lower chamfer and an upper end point of the upper chamfer. An included angle formed between the connected line and the normal of the upper surface of the light guiding plate is theta 3. The short edge of the light guiding plate is located at the front end of the light guiding plate. The incident light source is arranged under the lower chamfer of the light |
