ABSTRACT:
A display device includes a lower substrate, comprising reflective display pixel electrodes, an upper substrate and a liquid crystal layer provided between the substrates. A light source is provided on the upper substrate for illuminating the display electrodes through the liquid crystal layer. This arrangement provides a top light as an integrated structure within the liquid crystal display structure. The illumination can be efficiently provided to the pixel electrodes. This means that a light source pattern used can provide small light source areas.
