BACK LIGHT

摘要

PROBLEM TO BE SOLVED: To improve illuminating performance by suppressing luminance unevenness and luminance decrease near a light emission body in a back light for display body. SOLUTION: The back light 1 for display body is provided with a light shield tape 2 which is painted distinctively in >=2 colors with shading or has gradation coloration. The luminance unevenness is suppressed by the shaded light shield tape 2, so coloration adjustment near a light emission body in the back light 1 is facilitated. The adhesive of the light shield tape 2 is removed and the light shield tape is inserted into a light guide plate and fixed to prevent a luminance decrease due to the adhesive, thereby to enable high-luminance illumination. The back light like this is used to make electronic equipment small-sized and improve the illumination performance of a display part.
