A planar illumination device using LEDs is further increased and uniformized in brightness and thinned. A planar illumination device (10) has a light guide plate (2), LEDs (21-23) arranged on a side end face (3) of the light guide plate (2), and an FPC (11) on which the LEDs (21-23) are mounted. The LEDs (21-23) have exposed light emission sections (21a-23a) made from a translucent resin that seals the LED chips. The LEDs (21-23) are mounted on the FPC (11) with the light emission sections (21a-23a) projected from the outline of the FPC (11) and are arranged such that the light emission sections (21a-23a) are not projected from the side end face (3) of the light guide plate (2). Further, the planar illumination device has a reflection means (25) covering the light emission sections (21a-23a).
