An active matrix type electroluminescence display device comprises a plurality of display pixels GS 11 , GS 12 , GS 13 , etc. arranged in a matrix of rows and columns, each display pixel including an EL element, a first thin film transistor in which a display signal is applied to the drain and which is switched on and off in response to a select signal, a capacitance with one end connected to the source of the first thin film transistor for maintaining a voltage corresponding to the display signal, and a second thin film transistor for driving the EL element based on the display signal. The other ends of the capacitance of row display pixels are connected to and shared by a plurality of first capacitance lines HLA 1 , HLA 2 , HLA 3 , HLAi. Both ends of the plurality of first capacitance lines HLA 1 , HLA 2 , HLA 3 are connected to and shared by second capacitance lines HLB 1 and HLB 2 . A constant voltage is supplied to the second capacitance line.
