A film substrate (1) including string-shaped aluminum silicate (4) and a transparent resin (2). In the film substrate (1), the contained amount of string-shaped aluminum silicate (4) occupying the film substrate (1) is 0.5-50 mass%, 50% or more of the string-shaped aluminum silicate (4) has a long-axis dimension of 200 nm or more, and the haze value of the film substrate (1) is less than 10%. |
