摘要:
An optical element covering member is provided which can suppress degradation in display performance caused by warping and undulation. The optical element covering member includes at least one optical element, a support medium supporting the optical element; and a covering member covering the optical element and the support medium. In the above optical element covering member, the covering member has a Vicat softening point of more than 85° C., and at least one surface of the covering member, which covers the support medium, has a coefficient of thermal expansion in the range of 85% to 160% of the coefficient of thermal expansion of the support medium.
