摘要：
A notch is formed in a side of an optical sheet. As seen in plan view, the notch is shaped such that the maximum width of the notch as measured in the direction parallel to the line connecting both ends of a mouth portion of the notch is greater than the width of the mouth portion along the side of the optical sheet. Here, it is preferable that the notch be polygonal or have a curved shape as seen in plan view.
