Abstract: Provided are an edge-lit surface light source device and a liquid crystal display device, both of which are capable of two-dimensional local dimming without image contrast being reduced due to stray light. Even when light from LEDs that should be extracted by means of a light extraction pattern provided in a first section of a light guide plate is passed through the first section without being extracted, the light repeatedly strikes on a light absorbing layer formed in a second section, whereby much of the light is absorbed in the second section. Accordingly, little light from the LEDs is extracted from a third section, from which light from LEDs should originally be extracted, with the result that image contrast can be prevented from being reduced due to stray light.
