  • Publication number: 20200052231
    Abstract: When a base film used in a flexible display panel is bonded to a resin member for fixing the base film that is curved, the base film has creases by an environmental change such as temperature due to difference in linear expansion coefficient before and after a thermal shock. A buffer plate that is thin enough to be bent is provided between the base film used in a flexible display panel and the resin member. With the use of heat dissipation effect and heat equalization effect of the buffer plate, a structure around the panel capable of resisting the environmental change can be provided.
