Abstract
The present invention provides a liquid crystal display apparatus having a high brightness and a less number of constituent parts. By forming a plurality of dots each constituted by a small projecting portion or a small recess portion for changing a light at a predetermined angle from an incident surface of a light conductor plate toward a direction of a transmitting surface and properly controlling an angle of incline of a cross section, it is possible to irradiate an illuminating light having a suitable angle distribution from a light emitting surface toward a display element, thereby improving a brightness of the liquid crystal display apparatus.
