    摘要: An exemplary prism sheet (20) includes a light input surface (201), a light output surface (202) opposite to the light input surface, and a plurality of micro-depressions (205). The plurality of micro-depressions are defined in the light output surface and arranged in a skewed matrix. Each micro-depression has four side surfaces connected to each other, and a transverse width of each side surface decreases along a direction away from the light output surface and close to the light input surface. The present invention also provides a liquid crystal display device (200) using the above-described prism sheet.
