Document Type and Number:
Japanese Patent JP4468732
Kind Code:
B2
Abstract:
An edge-light type backlight system including a point light source, a light guide panel including a light incident part into which light enters from the point light source and a light emitting surface from which light is emitted, and an optical path-changing unit which changes a propagation path of light traveling inside the light guide panel. The light incident part includes a light incident surface on which a prism pattern is formed, the light incident surface facing the point light source, and first and second surfaces extending from the light incident surface in a direction in which light travels inside the light guide panel and adapted to reflect light passing through the light incident surface to reduce a direction angle, the first and second surfaces being opposite to each other with respect to an optical axis.
