  • Publication number: 20240086002
    Abstract: A display module includes a display area and a non-display area disposed outside the display area on a plane. The display module includes a base layer, a circuit device layer, a display device layer, a thin film encapsulation layer, and a touch sensing layer. An inorganic layer of the touch sensing layer contacts an inorganic layer of the circuit device layer exposed by an organic layer of the circuit device layer. An inorganic layer of the thin film encapsulation layer is disposed between the inorganic layer of the touch sensing layer and the inorganic layer of the circuit device layer to block a moisture penetration path which causes delamination of the thin film encapsulation layer.
