PURPOSE: To eliminate the rise of the luminance of the periphery of the effective illumination surface of a liquid crystal backlight. CONSTITUTION: A belt-like density modulation dot pattern whose density is reduced in an in-plane direction is printed and formed at the periphery of the reflection surface 11 of a reflection sheet 10 arranged on the rear side of the edge light panel 1 of the liquid crystal backlight A, and light going toward the base of the edge light panel 1 from an incident end face 3, a reflection end face 4 and a side end face 5 is partially absorbed, so that the quantity of the light reflected on the periphery of the surface of the edge light panel 1 is adjusted and the rise of the luminance at the part is eliminated. |
