Abstract

A liquid crystal display panel and a display device. The liquid crystal display panel includes a display region and an opening region in the display region; the display region includes a plurality of sub-pixels, the display region includes a first edge and a second edge opposite to the first edge, the display region includes a first region between the opening region and the first edge and a second region between the opening region and the second edge, an orthographic projection of the opening region on the first edge respectively coincides with orthographic projections of the first region and the second region on the first edge, the plurality of sub-pixels comprise a main sub-pixel in the first region and a secondary sub-pixel in the second region, and an area of the main sub-pixel is smaller than an area of the secondary sub-pixel.
