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, HLA3 are connected to and shared by second
capacitance lines HLB1 and HLB2. A constant voltage is supplied to
the second capacitance line.
