Claims

[Claims for Utility Model Registration] (1) Formed by attaching LED chips facing the opposite side to the front light emitting surface onto a circuit pattern provided on a thin transparent substrate, and covering each LED chip with a transparent resin material. A display device in which a reflective surface is provided on the back side and the periphery of a transparent resin layer, and the reflected light is emitted from the light emitting surface, is an LED in which a slope provided around the transparent resin layer is formed into a step-like reflective surface. A backlight for a liquid crystal display using. (2) The slope is 3 with respect to the axis passing through the LED chip.
A backlight for a liquid crystal display using an LED according to claim 1, which has an angle of 0 to 45 degrees. (3) A backlight for a liquid crystal display device using an LED according to claim 1, wherein a conical concave portion is provided on the back side of the transparent resin layer centered on an axis passing through the LED chip.
