摘要： The present disclosure provides a display panel and a display apparatus, which belongs to the field of display technologies. The display panel includes a plurality of subpixels on a side of a substrate. Each subpixel includes a first circuit and a second circuit. The first circuit and the second circuit control a voltage at a first node under control of a first control line and a second control line. At least two subpixels in the plurality of subpixels share the same first node. Therefore, the sum of the number of a plurality of first control lines and the number of a plurality of second control lines in the display panel is less than or equal to the number of subpixels in a column direction. Correspondingly, a small number of signal lines need to be disposed in the display panel, which facilitates high-resolution design of the display panel.
