Light redirecting film

A liquid crystal display (LCD) comprising:

• a liquid crystal panel;
• and
• a light redirecting film in a sandwich-laminated structure attached in front of the displaying side of the liquid crystal panel, comprising:
• a first layer having a first refraction index of n1;
• a second layer having a third refraction index of n3;
• and
• an intermediate layer having a second refraction index of n2, disposed between the first layer and the second layer, including a first grating surface having a plurality of first gratings extending in a first grating direction and a second grating surface opposite to the first grating surface having a plurality of second gratings extending in a second grating direction, wherein the first grating direction and the second grating direction cross each other at an angle of 90°±10°, and the first grating surface and the second grating surface of the intermediate layer are gap-filled and planarized with the first layer and the second layer respectively, and n2 is greater than n1 and n3;
• wherein, gamma values reflecting to the contrast ration and color saturation of the liquid crystal display (LCD) are greater than 0.9 at different horizontal and/or vertical viewing angles ≤80 degrees.
