摘要： Each data line includes base parts covering contact holes and line parts extending in an array direction of pixel circuits and connecting adjacent base parts to each other. The line parts have a smaller width in a direction perpendicular to the array direction than the base parts and are connected to the base parts while being offset in the direction perpendicular to the array direction from each other on both sides of at least two base parts that include first and second base parts. A connection position of the first base part with the line part on one side among both sides of the base units is located on the pixel circuit side with respect to the other side, and a connection position of the second base part on the one side is located on an opposite side to the pixel circuit side with respect to the other side.
