Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a lenticular lens sheet by which the boundary of a light shielding pattern is prevented from getting irregular in a method for forming a light shielding pattern layer in a self-alignment system. SOLUTION: In the method for manufacturing the lenticular lens sheet, a lens base plate 2 equipped with a lens part 1 condensing incident light in a predetermined direction is formed, and a masking sheet 30 is stuck on the lens base plate 2 so as to form a contact area with the top part of the lens part on a surface where a sticking layer constituting at least a part of the masking sheet 30 is formed, then parallel light beams are radiated as incident light beams from the masking sheet 30 side to form the light shielding pattern layer 3 having an incident light passing part corresponding to such shape that the incident light beam passes on the side of an emitting surface where the incident light beam passing through the lens part 1 including the contact area is emitted.

Abstract: PROBLEM TO BE SOLVED: To provide an optical sheet having high light utilization efficiency.
SOLUTION: The optical sheet 1 for a backlight is constituted so that a diffusion sheet 4 and a prism sheet 5 are arranged in this order from the side of a light source. Prisms 6 are arranged in parallel on the side of the light emission surface of the prism sheet 5. The light emission surface of the diffusion sheet 4 is stuck to the light entrance surface of the prism sheet 5 while interposing a light reflective layer 7 between them. The light reflective layer 7 is disposed like a stripe perpendicular to the longitudinal direction of each prism 6. As a result, since the light made incident on the stuck portion can be restrained from entering each prism at a large incident angle, light beams can be concentrated effectively to the front surface direction. Moreover, a moire obstruction owing to the interference of each prism with a pitch of the light reflective layers is hardly caused.

Abstract translation: 要解决的问题：提供一种光利用率高的光学片。 解决方案：用于背光的光学片1被构造成从光源侧依次排列扩散片4和棱镜片5。 棱镜6在棱镜片5的发光面的一侧平行地配置。漫射片4的发光面粘贴在棱镜片5的光入射面上，同时在它们之间插入光反射层7 。 光反射层7被设置成与每个棱镜6的纵向方向垂直的条带。结果，由于入射到粘贴部分上的光可以被抑制在大的入射角进入每个棱镜，所以光束可以 集中在前表面方向。 此外，由于每个棱镜与光反射层的间距的干涉而导致的莫尔条纹阻塞很难引起。 版权所有（C）2009，JPO＆INPIT
