Light guide plate having visual angle adjusting member and liquid crystal display apparatus having the same

摘要

Disclosed is a light guide plate for improving front visual angle characteristics. Either a pyramidal recession having at least three sidewalls and a predetermined depth or a pyramidal protrusion having at least three sidewalls and a predetermined height is formed on a light emitting surface of the light guide plate. Accordingly, it is possible to increase the brightness of the front visual angle without using a prism and diffusion sheets or with a reduced number of prism sheets. Also, an LCD apparatus using the light guide plate has a reduced weight and volume compared with conventional LCDs.
