Abstract: A display panel and a display device are provided. The display panel includes an array substrate and a color film substrate forming a cell aligning structure, and a liquid crystal layer arranged between the array substrate and the color film substrate. The thickness of the liquid crystal layer is 1.5 um to 3 um. The disclosure reduces the thickness of the liquid crystal layer and greatly reduces the falling edge time of the display panel without greatly affecting the transmittance, thereby reducing the overall response time of the display panel. This can be particularly useful in situations where a moderate light transmittance is required.
