Abstract: A display device may include a conductive pattern disposed on a substrate. A passivation layer may be disposed on the conductive pattern. A first shielding electrode and a second shielding electrode that may be disposed on the passivation layer may be spaced apart from each other. A first electrode may be disposed on the first shielding electrode. A second electrode may be disposed on the second shielding electrode. A light emitting element may be electrically connected between the first electrode and the second electrode. A first distance between the first shielding electrode and the second shielding electrode may be less than a second distance between the first electrode and the second electrode.

Abstract: A display device includes a first display substrate and a second display substrate. The first display substrate includes a first base, a first electrode disposed on the first base, a second electrode spaced apart from the first electrode, and a light emitting element disposed between the first electrode and the second electrode. The second display substrate faces the first display substrate and is configured to receive light emitted from the light emitting element. The second display substrate includes a second base, a first color filter disposed on a surface of the second base, and a first wavelength conversion pattern disposed on the first color filter. The first wavelength conversion pattern includes a first surface facing the first display substrate, and a second surface facing the first surface and the first color filter. The first surface includes a curved surface portion recessed toward the second surface.
