Abstract
The present invention is directed to a display device comprising a display fluid layer sandwiched between a first substrate layer and a second substrate layer, and a light-enhancing layer between the display fluid layer and the second substrate layer. The light-enhancing structure can enhance the colors displayed by the display device, especially the colors displayed through lateral switching of the charged pigment particles in an electrophoretic fluid.
