Abstract
A backlight kit includes a base member, a covering member, a slim-type light guide element and an illumination module. The covering member is combined with the base member. The slim-type light guide element and the illumination module are arranged between the base member and the covering member. After the illumination module emits a light beam to the slim-type light guide element, the light beam is transferred through the slim-type light guide element. Consequently, a luminance gradient region is formed on the surface of the covering member.
