Abstract

A display panel and a display device are provided. The display panel includes a plurality of gate lines, a plurality of data lines and a plurality of sub-pixels (11) formed by the plurality of gate lines and the plurality of data lines intersecting with each other, and the plurality of sub-pixels (11) forming an array. In the array formed by the plurality of sub-pixels (11), a ratio of a width in a row direction to a height in a column direction of each sub-pixel (11) is greater than 1:3, and a first row of sub-pixels and a second row of sub-pixels are alternately arranged in the column direction. Each sub-pixel (11) in the first row of sub-pixels and its adjacent sub-pixel in the second row of sub-pixels have different colors. Each sub-pixel (11) in the second row of sub-pixels and its adjacent sub-pixel in the first row of sub-pixels have different colors. The sub-pixel (11) in the second row of sub-pixels and the sub-pixel (11) in the first row of sub-pixels which are provided in a same column are staggered by a distance of d in the row direction, where 0≤d<W/2, and W is the width in the row direction of each sub-pixel. In the case that a display resolution is guaranteed, the number of the data lines are reduced, and requirements on the production technology are lowered; besides, the data lines are relatively smooth, and resistance of the data lines is reduced, and voltage load on the display panel is reduced.
