Abstract
The present invention is directed to luminance enhancement structure for reflective display devices. The luminance enhancement structure comprises grooves and columns, wherein said grooves have a triangular cross-section and a top angle, and said grooves and columns are in alternating order and in a continuous form in one direction. The luminance enhancement structure not only can reduce the total internal reflection, but also especially can enhance the on-axis brightness of a display device.
