A lens substrate (microlens substrate 1 ) having a first surface and a second surface opposite to the first surface is disclosed. Light is allowed to enter the lens substrate from the first surface thereof and then exit from the second surface thereof. The lens substrate includes: a plurality of convex lenses (microlenses 21 ) formed on the first surface of the lens substrate from which the light is allowed to enter the lens substrate; and a colored portion 22 provided on the first surface of the lens substrate with the plurality of convex lenses.
