BACKLIGHT AND DISPLAY MODULE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve such a problem that it is impossible to equalize luminance of the whole display screen.

SOLUTION: A backlight has at least one light emitter having a shape extended in one direction, a light diffusing means having a flat shape and a light guide means provided between the light diffusing means and the light emitter and having a plurality of guide faces in parallel with the center axis of the light emitter. At least part of the plurality of guide faces changes an angle of incident light from the light emitter in a direction separating from the center axis of the light emitter so as to make the incident light incident on the surface of the light diffusing means.
