  • Publication number: 20190228711
    Abstract: A display apparatus includes a display panel and a driving circuit. The display panel includes signal lines extending in a column direction, scanning lines extending in a row direction, and lead-out lines extending in the column direction. Each of the lead-out lines intersects with corresponding one of the scanning lines at an intersection and is electrically coupled to the corresponding one of the scanning lines at a node. The node is disposed at the intersection or in a region surrounding the intersection. The driving circuit supplies corresponding one of the signal lines with a signal pulse corresponding to an image signal, and supplies corresponding one of the lead-out lines with a selection pulse having a peak value based on a distance from one end of the corresponding one of the lead-out lines to the corresponding node, after increasing the peak value with an increase in the distance.
