Title:
ILLUMINATION APPARATUS AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/122060
Kind Code:
A1
Abstract:
Provided is an illumination apparatus which prevents variations in the distance between the light-receiving surface of a light guide plate and a light source. Also provided is a display device which incorporates the illumination apparatus. The light guide plate (11), which constitutes a backlight unit (49), receives light through a light-receiving surface (11Sa) with the light-receiving surface (11Sa) oriented toward the light being emitted. In the backlight unit (49), pillars (PL) extend to intersect the direction of emission from an LED (32) and are thus brought into contact with a device-carrying board (31) and the light guide plate (11), which are superposed one on the other, thereby securing the device-carrying board (31) and the light guide plate (11).
