Abstract: A display panel includes heating lines each including part located in a display region, and a heating bus and a power supply pin located in a non-display region. The heating bus is electrically connected to the power supply pin and the heating lines. The display region includes first and second sub-regions, the heating lines include first and second heating lines. One first heating line is located in the first sub-region. One second heating line is located in the second sub-region. A length of the heating bus connected between one first heating line and the power supply pin is greater than a length of heating bus connected between one second heating line and the power supply pin. An arrangement density of first heating line is greater than that of the second heating line, or a resistance of the first heating line is smaller than that of the second heating line.

Abstract: Provided are a display panel and a display device. Along a column direction of the matrix, adjacent N rows of sub-pixels form a pixel unit group, N scanning lines of a same pixel unit group are electrically connected, and sub-pixels of the same pixel unit group are electrically connected to different data lines; a length of a first edge of the sub-pixel along the column direction of the matrix is smaller than a length of a second edge along a row direction; along the column direction of the matrix, adjacent N sub-pixels form a pixel unit; among N switch transistors of a same pixel unit, orthographic projections of at least two switch transistors on a preset plane at least partially overlap; among N data lines of the same pixel unit, an orthographic projection of at least one data line overlaps an orthographic projection of at least one pixel electrode.
