A display capable of inhibiting a logic composition circuit from outputting a signal to a gate line or a drain line at unintentional timing is obtained. This display comprises a shift register circuit (52, 53, 54, 55, 502, 503, 504, 505, 512, 513, 514, 515, 522, 523, 524, 525, 532, 533, 534, 535, 542, 543, 544, 545) including a logic composition circuit portion (81, 82, 83, 801, 802, 803, 811, 812, 813, 821, 822, 823, 831, 832, 833, 841, 842, 843) constituted of a plurality of first conductive type transistors turned on with a first voltage supply source for receiving a first shift signal and a second shift signal and outputting a shift output signal by logically compositing the first shift signal and the second shift signal with each other. At least either a first shift register circuit portion or a second shift register circuit portion includes a reset transistor (NT39, NT49, PT39, PT49) for resetting the voltage supply source of a node outputting the first shift signal or the second shift signal to a second voltage supply source not turning on the transistors of the logic composition circuit portion in response to a prescribed drive signal.
