摘要 |
A surface light source device includes a light guide plate disposed on an upper surface of a liquid crystal panel unit and a linear light source disposed extending in a direction parallel to a side surface of the light guide plate. A plurality of linear prisms are formed on an upper surface of the light guide plate in a manner of extending in a direction oblique to the side surface. A light irradiated from the linear light source to the light guide plate through the side surface is reflected by a reflecting surface formed by each of linear prisms to be irradiated onto the liquid crystal panel unit provided below a lower surface of the plate. A height of the reflecting surface of each of linear prisms is changed in a lengthwise direction thereof.
