Abstract
A light shielding member of the present invention may include a first polarizing plate, a second polarizing plate facing the first polarizing plate, and a thermosensitive sheet interposed between the first polarizing plate and the second polarizing plate, in which the first polarizing plate and the second polarizing plate may be positioned so that their respective transmission axes are different from each other. The thermosensitive sheet may include a side chain crystal polymer that crystallizes at a temperature lower than the melting point and exhibits fluidity at a temperature of the melting point or higher where the side chain crystal polymer is oriented in one direction.
