A plurality of source lines extending parallel to each other while alternately turning between a plurality of pixel electrodes provided in a delta arrangement, each have a plurality of first linear portions each extending along a side of the corresponding pixel electrode, a plurality of second linear portions each linked to the corresponding first linear portion and extending along a side of the corresponding pixel electrode to a middle portion of the side, and a plurality of protruding portions each extending from one end of the corresponding second linear portion along a side of the corresponding pixel electrode.

Active matrix substrate and liquid crystal display device

An active matrix type display panel, used as a display-use panel, has pixel patterns each having aperture sections. The aperture sections are set to have a width satisfying the following inequality,0&#x3c;(minimum width of the aperture sections in the pixel)/(maximum width of the aperture sections in the pixel)&#x2266;0.037, or0.130&#x2266;(minimum width of the aperture sections in the pixel)/(maximum width of the aperture sections in the pixel)&#x3c;1.

Display panel and display apparatus

An object of the present invention is to regulate the thickness of a liquid crystal layer between faces of substrates more uniformly and accurately than the prior arts, to eliminate an orientation disturbance caused in a rubbing treatment and to prevent a display performance from degraded, by introducing columnar spacers which have a firm adhesion force to an active matrix substrate. On an active matrix substrate which has switching elements arranged in a matrix form and pixel electrodes, columnar spacers are formed in vicinities of the switching elements on gate lines or source lines connected to the switching elements, or formed on the switching elements. Further, for giving a rubbing process to a resin film for an orientation film which is formed on the active matrix substrate, a rubbing direction is set to be a direction where an orientation-disturbed region formed in the rear of the columnar spacers does not overlap the pixel electrode substantially.
