Display panel and display device

The invention discloses a display panel and a display device. In the display panel, an optical membrane is further arranged at the side, away from an array substrate, of a color film substrate, the refractive index of the optical membrane is smaller than that of a color film area of the color film substrate, so that light rays emitted by a second subpixel are completely reflected at the contact face of a first color resistor and the optical membrane, and/or light rays emitted by a first subpixel are completely reflected at the contact face of a second color resistor and the optical membrane, and accordingly the situation is avoided that the first subpixel and/or the second subpixel are/is emergent from the color resistors right opposite to the adjacent subpixels. Accordingly, the color cast phenomenon of images displayed on the display panel is reduced. 本申请公开了种显示面板及显示装置，其中，在所述显示面板中，在彩膜基板背离阵列基板侧还设置有光学膜层，所述光学膜层的折射率小于所述彩膜基板的彩膜区的折射率，以使第二子像素出射的光线在所述第色阻与所述光学膜层的接触面处发生全反射，和/或使所述第子像素出射的光线在所述第二色阻与所述光学膜层的接触面处发生全反射，从而避免第
