| 摘要 |
This illumination device is provided with light sources (15) arranged in one direction along a line or side-by-side, a light-guide plate (14) which guides light incident from an incidence surface (14a) on the side circumferential surface across from the light sources (15) and emits planar illumination light from an exit surface (14b) on the front surface, a chassis (13) which covers and supports the light sources (15) and the periphery of the light-guide plate (14), a scattering pattern (18) which is formed on the back surface (14c) of the light-guide plate (14), and positioning units (14g) which are provided jutting from the side peripheral surface of the light-guide plate (14) for positioning the light-guide plate (14) by fitting with the inner surface of the chassis (13), wherein the scattering patttern (18) is provided so as to extend on the positioning units (14g). |
