摘要： This disclosure relates to a light modulation panel and a display device. The light modulation panel comprises: a color separation grating plate having a plurality of light-transmissive microstructures; a reception substrate located on a light exit side of the color separation grating plate and spaced away from the color separation grating plate; and an optical waveguide layer located on a light exit side of the reception substrate. According to technical solutions of this disclosure, the optical waveguide layer can modulate the exit light into collimated light. As a result, cross-color phenomenons of the display device can be effectively improved, and thereby the display quality is enhanced. In addition, by adjusting a structure of the optical waveguide layer, the exit light can also be emitted out at a preset angle such that the display device can be applied in occasions such as 2D display, 3D display or privacy protection.
