A pixel circuit of at least one embodiment of the present invention includes: a display element whose light emitting luminance is controlled by a supplied current; at least one first switching element section whose output current characteristic shows a saturation characteristic in response to an input variable serving as a grayscale signal; and at least one second switching element section whose output current characteristic shows a linear characteristic in response to an input variable serving as a grayscale signal. A first current supply line which outputs a current determined by the first switching element section and a second current supply line which outputs a current determined by the second switching element section are combined, and then succeeded by a current supply line of the display element. This makes it possible to provide a pixel circuit and a display device which can generate higher peak luminance while sufficiently securing a voltage range which causes an appropriate normal grayscale display within a predetermined driver voltage output range.
