Zusammenfassung:A display apparatus includes a plurality of luminescent devices aligned periodically in a row direction and in a column direction, a plurality of pixel circuits aligned periodically in a row direction and in a column direction for supplying an electric current to each of the luminescent devices, a plurality of data lines each connected commonly to the pixel circuits aligned periodically in the column direction for supplying signal currents to these pixel circuits, and a plurality of column-current generating circuits connected to the plurality of data lines respectively for supplying signal currents to corresponding data lines. Each of the column-current generating circuits have a plurality of transistor devices arranged in a distributed manner and including main electrodes respectively connected in parallel and control electrodes commonly connected. The plurality of transistor devices are arranged in the row direction at a pitch equal to or n times, with n being a natural number not smaller than two, of the alignment period in the row direction of the plurality of luminescent devices and arranged in the column direction at a constant pitch.
