ABSTRACT:
An active matrix type electroluminescence display device comprises a plurality of display pixels GS11, GS12, GS13, 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 HLA1, HLA2, HLA3, HLAi. Both ends of the plurality of first capacitance lines HLA1, HLA2, HLA3are connected to and shared by second capacitance lines HLB1and HLB2. A constant voltage is supplied to the second capacitance line.
