A reflective polarizing plate apparatus includes a reflective polarizing plate that transmits first linearly polarized light and reflects second linearly polarized light polarized in a direction substantially perpendicular to the direction in which the first linearly polarized light is polarized, a holding member that accommodates and holds the reflective polarizing plate, and a first biasing member that biases a glass surface of the reflective polarizing plate accommodated in the holding member.
