Liquid crystal display device |
摘要 |
An LCD device has scratch-resistant property without using a protection sheet and can provide enhanced brightness. The LCD device includes a light path regulating member. The member includes a first prism sheet having first prisms of which apex has a round shape. The first prism sheet concentrates light supplied from a lamp to output the concentrated light. An anti-glare polarizing plate uniformly polarizes polarized planes of the concentrated light and provides the polarized light to the lower substrate. The anti-glare polarizing plate is arranged below the lower substrate of an LCD panel, and an uppermost prism sheet of optical sheets is non-matte-treated and has round-treated apexes. In spite of the absence of the protection sheet, the scratch-resistant property of the uppermost prism sheet and the brightness of the LCD panel may be enhanced.
