    • 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.
    • 液晶显示装置具有耐刮擦性能,不使用保护片,可提供更高的亮度。 LCD装置包括光路调节部件。 该构件包括具有顶点具有圆形形状的第一棱镜的第一棱镜片。 第一棱镜片集中从灯提供的光以输出集中的光。 抗眩光偏光板使聚光的偏振面均匀地偏振,并向下基板提供偏振光。 防眩光偏振板配置在LCD面板的下基板的下方,最上方的光学片的棱镜片未经磨光处理,具有圆形处理的顶点。 尽管不存在保护片,但是可以提高最上面的棱镜片的耐擦伤性和LCD面板的亮度。
