Abstract
There is disclosed a transflective liquid crystal display having pixels each including a reflective region and a transmissive region. The aperture ratio of the pixels can be enhanced. End portions of two adjacent color filters are overlapped to form an optically shielding portion for each pixel. The optically shielding portion and the reflective region cooperate to form an optically shielding film acting as a black matrix for the transmissive region. The aperture ratio is enhanced by improving the positional relationship between the reflective regions and the color filters.
