<P>PROBLEM TO BE SOLVED: To provide a display device capable of adjusting the emission period into a plurality of types, while reducing the cost. <P>SOLUTION: A control pulse is applied to an emission control line DSL, and on/off states of emission control transistors Tr3n and Tr3p are controlled, thereby controlling the emission operation and the non-emission operation of an organic EL element 12. Each sub-pixel is constituted of one of sub-pixels 11Rn and Bn, by using an n-channel emission control transistor Tr3n and a sub-pixel 11Gp, by using a p-channel emission control transistor Tr3p. The emission periods of the sub-pixels 11Rn, 11Bn, and 11Gp are adjusted into two types. The sub-pixels 11Rn and 11Bn and the sub-pixel 11Gp are both commonly connected to one emission control line DSL. The number of used emission control lines is reduced, as compared with that in conventional types. <P>COPYRIGHT: (C)2011,JPO&INPIT |
