A light guide plate raw sheet with mask membranes comprises a light guide plate raw sheet (2) and mask membranes (3A, 3B) attached to the two surfaces of the raw sheet (2) respectively. One main surface of the raw sheet (2) is a printing surface (2a) of a printing light-dot pattern, and the other main surface of the raw sheet (2) is a non-printing surface (2b) of a non-printing light-dot pattern. The hazes of the mask membranes (3A, 3B) are below 40% and represent the turbidities (opacities) of the membranes. |
