<P>PROBLEM TO BE SOLVED: To wipe out the fear of lowering in yield due to increase in cost. <P>SOLUTION: A reference current flowing part is arranged in a peripheral part of a display device as a reference circuit 100, and is shared by a plurality of pixels 110. When a voltage according to brightness data is applied to a data line Data, currents according to a gate voltage are made to flow through a transistor Tr4 and a transistor Tr5, respectively. When a scanning line GL becomes high, a transistor Tr3 is turned on, and the gate voltages of a transistor Tr2 and a transistor Tr1 are brought at the same level. As a result, a current is made to flow through the transistor Tr2 according to a driving capacity ratio of the transistor Tr1. <P>COPYRIGHT: (C)2003,JPO |
