Title: Front light device
Inventor: IWATA TAKAO
IPC: F21V8/00
Filed: 2001-08-17
Abstract: PROBLEM TO BE SOLVED: To effectively use the light of a front light device for a reflection type liquid crystal display device by emitting many light beams from the under surface of a light guide plate and hardly emitting the light beams to the upper surface. SOLUTION: The front light device has a transparent light guide plate (10) and a light source (2) provided in the vicinity of the end surface of the light guide plate, and the light guide plate has a projected part (22) which has a rectangular or trapezoidal cross section on the under surface. In one embodiment, the ratio of a width W to a height h at the bottom surface of the projected part on the under surface of the light guide plate is h/W>0.7, and the angle formed by the side surface of the projected part with the flat surface of the bottom surface of the light guide plate is within a range of 90 to 120 degrees.  The light which advances in the light guide plate is totally reflected by the upper surface (20) and the flat surface part of the under surface of the light guide plate (21), and is emitted down below the light guide plate when the light enters into the projected part of the bottom surface. There is little light emitted from the upper part of the light guide plate, and the light is thus effectively used.
