PROBLEM TO BE SOLVED: To eject uniform light from a light guide structure.SOLUTION: A first crimp area 50a having a crimp at an area adjacent to a bent part 32a is formed at a surface of a transparent material main body 34a, not adjacent to a liquid crystal panel 24, that is continuous to the bend part 32a formed in continuous with an incident part 30a and bent in a direction along the liquid crystal panel 24 and further a second crimp area 52a provided with a more fine crimp than that of the first crimp area 50a is formed at an area adjacent to the first crimp area 50a. Lighting light incident from the incident part 30a is dispersed into a wide range by the crimp formed at the first crimp area 50a and the lighting light is not attenuated with a finer crimp formed at the second crimp area 52a and the light is guided to a deeper side of the transparent material main body 34a.SELECTED DRAWING: Figure 3 |
