Abstract: In a groove-formed body, recesses and protrusions are formed in a resin plate by irradiating a laser. Each of four recesses extend from an intersection point thereof. When forming each of the recesses in the resin plate, a portion at the intersection point of the recesses is an irradiation stop position of the laser, and an amount of heat generated by the laser on the resin plate is decreased. This enables a protrusion to be suppressed from being formed on either side of the intersection point of the recesses, and enables a protrusion to be suppressed from being disposed between the portion of the recesses at the intersection point, and a portion other than at the intersection point.

The second polarizing plate is arranged such that the first display region at least partially overlaps with the second display region. At least a part of one of the first display region and the second display region includes a mixed part in which a polarization part with a polarizing function and a non-polarization part without any polarizing function are mixed.

Abstract: In a groove-formed body, a recess and protrusions are formed on a resin plate by irradiation with a laser. When forming the recess and the protrusions on the resin plate, the laser is irradiated onto the resin plate plural times. Irradiation of the laser onto the resin plate is thus temporarily paused to cool the resin plate, enabling the portion of the resin plate irradiated by the laser to be suppressed from igniting and enabling a depth dimension of the recess and a height dimension of the protrusions to be made larger.
