EDGE-LIGHT TYPE PLANAR LIGHT SOURCE DEVICE

The present invention makes it possible to (i) obtain a sufficient and uniform luminance on an entire surface, which is irradiated with light, of a light guide plate and (ii) achieve a reduction in cost. LED light source substrates (140a) and (140b) are each configured to emit light having a first l...

More Information
Summary:The present invention makes it possible to (i) obtain a sufficient and uniform luminance on an entire surface, which is irradiated with light, of a light guide plate and (ii) achieve a reduction in cost. LED light source substrates (140a) and (140b) are each configured to emit light having a first luminance gradient on an edge of a range, to be irradiated with light, which first luminance gradient is smaller than a second luminance gradient of light having a substantially uniform luminance on an entire range to be irradiated with light.
