Abstract:
1. A display device comprising an element board and a counter board, the element board including: a plurality of data signal lines for transmitting a plurality of data signals; a plurality of scanning signal lines crossing the data signal lines; a plurality of pixel formation portions disposed in a matrix form, the pixel formation portions being provided in a vicinity of their respective intersections between the plurality of data signal lines and the plurality of scanning signal lines crossing the data signal lines; and a plurality of dummy pixel portions, each being disposed adjacent to an outermost one of the pixel formation portions, the counter board being provided so as to be opposed to the element board, such that electro-optical elements for effecting a display are sandwiched between the counter board and the element board, wherein the pixel formation portions each include a storage capacitance portion having two electrodes for holding a potential in accordance with a signal supplied from a corresponding one of the data signal lines, wherein the dummy pixel portions include at least one component equivalent to any one of a plurality of light blocking effect components for forming a predetermined circuit included in the pixel formation portions, and an area of the component included in the dummy pixel portion, when viewed from a position substantially vertically away from a principal surface of the element board, is smaller than that of each of the components included in the pixel formation portions, and the dummy pixel portions include an electrode equivalent to one of the two electrodes included in the storage capacitance portion, the electrode included in the dummy pixel portions has a smaller area than that of the one electrode included in the pixel formation portion, wherein the dummy pixel portions each include a code notation portion in which to note a predetermined code, and wherein the component included in the dummy pixel portions is disposed so as not to prevent notation of the code.
