Display device having shared column lines

摘要

A display device having at least a plurality of pixel circuits, connected to signal lines to which data signals in accordance with luminance information are supplied, arranged in a matrix, wherein pixel circuits of odd number columns and even number columns adjacent sandwiching an axis in a column direction parallel to an arrangement direction of the signal lines have a mirror type circuit arrangement symmetric about the axis of the column direction, and there are lines different from the signal lines between signal lines of adjacent pixel circuits.

1. A display device comprising:
a plurality of pixel circuits arranged in a matrix; signal lines configured to supply data signals; first lines arranged in a column direction; second lines arranged in the column direction, wherein one of the second lines is shared by pixel circuits in a first column of the pixel circuits and a second column of the pixel circuits, wherein one of the first lines is shared by pixel circuits in the second column and a third column of the 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 second lines is located between the first column and the second column, but none of the first lines are located between the first column and the second column, wherein the one of the first lines is located between the second column and the third column, but none of the second lines are located between the second column and the third column, and wherein a given one of the plurality of pixel circuits comprises:
a sampling transistor configured to sample the data signal;a capacitor configured to store a voltage based on the data signal;a first transistor connected between one of the first lines and an anode electrode of a light emitting element;a second transistor configured to supply a potential voltage from one of the second lines to the capacitor.
