Abstract
A display panel structure for suppressing vertical smear is provided for an active matrix type liquid crystal display device employing in-plane switching. Each of pixel regions arranged in a matrix form and constituting a display panel takes the form of a rectangle having a side along an adjacent video signal line shorter than a side along a scan signal line. A display electrode and reference electrodes arranged in each pixel region respectively have a strip-like shape extending in a direction orthogonal to a video signal line.
