Abstract:
1. A display device having a plurality of pixels arrayed so as to form a matrix-like pattern, the display device comprising: an organic electroluminescence element that is formed in a longitudinally oblong shape in each pixel; a drive thin-film transistor that is formed in each pixel and that feeds a current to the organic electroluminescence element to make the organic electroluminescence element emit light; and a control thin-film transistor that controls operation of the drive thin-film transistor, wherein the drive thin-film transistor is formed in a laterally oblong shape, a gate signal line and a source signal line connected to the control thin-film transistor are arranged in a matrix-like pattern, the organic electroluminescence element is arranged so that a longer-side direction thereof is parallel to the source signal line, the drive thin-film transistor has a channel region formed in an elongate shape, the channel region being arranged so that a longer-side direction thereof is parallel to the gate signal line and to shorter sides of the organic electroluminescence element, and being disposed over a substantially entire area of each pixel along the gate signal line, and the drive thin-film transistor and the control thin-film transistor have a semiconductor layer formed of non-crystal silicon.
