  • Publication number: 20240306420
    Abstract: A display device includes a first base on which a display area and a non-display area are defined; a first support member disposed on the first base and located in the non-display area; a light emitting element disposed on the first base and located in the display area; an encapsulation layer which disposed on the light emitting element; a second base disposed on the encapsulation layer; a color filter disposed between the second base and the encapsulation layer, where the color filter overlaps the light emitting element; a wavelength conversion pattern disposed on the color filter; and a sealing member disposed between the first base and the second base and located in the non-display area, where the sealing member is located between the display area and the first support member and overlaps the encapsulation layer.
