摘要： A display device includes a display panel, an optical member and an elastic inter-module fixing member. The optical member is disposed under the display panel. The elastic inter-module fixing member is disposed between the display panel and the optical member and overlapping the optical member in a top plan view. A friction coefficient of the inter-module fixing member with respect to each of the display panel and the optical member is larger than a friction coefficient of the display panel with respect to the optical member, to fix positions of the display panel and the optical member solely by the inter-module fixing member therebetween.
