Patent ID: 8519915

Claim:
A display device comprising: a plurality of pixel circuits arranged in a matrix; signal lines for supplying data signals; precharge potential lines arranged in a column direction; power supply potential lines arranged in the column direction, wherein one of the power supply potential lines is shared by pixel circuits in a first column of the plurality of pixel circuits and a second column of the plurality of pixel circuits, wherein one of the precharge potential lines is shared by pixel circuits in the second column and a third column of the plurality of pixel circuits, wherein the second column is adjacent to the first column, the second column is adjacent to the third column, and the second column is between the first column and the third column, wherein the one of the power supply potential lines is located between the first column and the second column, but none of the precharge potential lines are located between the first column and the second column, and wherein the one of the precharge potential lines is located between the second column and the third column, but none of the power supply potential lines are located between the second column and the third column.
