A display device includes a pixel array in which a plurality of display pixels are arranged in a two-dimensional manner which is divided into a plurality of column groups composed of the display pixels of a predetermined number of columns, a signal drive circuit which produces a signal current based on display data, and sequentially outputs, in time series via a common terminals, the signal current that corresponds to the display pixels for one row of the pixel array for each of signal currents that correspond to each of the column groups, and a current latch circuit which sequentially captures and holds the signal currents output from the signal drive circuit for one row of the pixel array, generates gradation currents and simultaneously supplies the gradation currents to the plurality of data lines, wherein the pixel array and the current latch circuit are formed on a display panel substrate.
