Abstract
A display device includes a pair of first and second light sources arranged on a printed circuit board in a spaced-apart but close relationship to each other. A light-shielding tab is interposed between the first and second light sources for shielding light from an illuminated one of the pair of light sources from being transmitted to the other one of the light sources.
