Abstract
A miniature backlight kit includes a covering member, a light-shading element, a light guide element, a housing and a light-emitting unit. The light-emitting unit is disposed within a first concave structure of the light-shading element. The light-shading element is disposed within a second concave structure of the light guide element. The light guide element is covered by the lateral wall of the housing. The light-emitting unit emits a light beam. The light beam is reflected to the lateral wall of the housing by the light guide element. Consequently, a luminance gradient region is formed on the surface of the lateral wall of the housing.
