ABSTRACT:
An exemplary prism sheet includes a light input surface, a light output surface opposite to the light input surface, and a plurality of micro-protrusions formed on the light output surface and arranged in a skewed matrix. Each micro-protrusion includes at least three side surfaces connected in turn. A transverse width of each side surface decreases along a direction away from the light output surface. A liquid crystal display device using the prism sheet can efficiently decrease moiré patterns between the prism sheet and the liquid crystal display panel.
