Abstract

A display panel includes a display region with a thin film transistor and a plurality of data lines and a non-display region. Thin film transistor includes a gate, a source region and a drain region, data lines include a plurality of first type data lines which are located at an edge of display region and close to a side of non-display region. First type data line includes a first sub-data line extending in a first direction, a conductive connection line extending in a second direction and a second sub-data line extending in a first direction. First sub-data line is connected with source region or drain region. A first insulating layer is between conductive connection line and first sub-data line. A second insulating layer is between second sub-data line and conductive connection line, and second sub-data line is closer to a central axis of display panel than first sub-data line.
