Claim Text:
1. A semi-transmissive display apparatus comprising: a plurality of signal lines and a plurality of scan lines formed on a first substrate; a plurality of pixels arranged in rows and columns at intersections of the plurality of signal lines and the plurality of scan lines; a respective reflective electrode arranged in each of the plurality of pixels; a transparent electrode formed on a second substrate facing the first substrate; and a liquid crystal layer between the reflective electrodes and the transparent electrode; wherein: the reflective electrodes include openings, each of the pixels has a memory; the reflective electrode in each of the pixels is divided into a plurality of sub-electrodes that are weighted in terms of area, and the display apparatus is configured to perform an area-based grayscale operation to express gray scales based on a combination of the areas of sub-electrodes, wherein the reflective electrodes are formed on a planarization film with a portion of the planarizing film between reflective electrodes being removed in a transmissive region.
