Abstract
The invention relates to a display device and a splicing type display device. The display device includes: a substrate including a display area including an emission area and a light blocking area, and a non-display area adjacent to the display area; a thin film transistor layer disposed on the substrate and including a thin film transistor; a light emitting element layer disposed on the thin film transistor layer and including a light emitting element; a wavelength conversion layer provided on the light emitting element layer, the wavelength conversion layer converting a peak wavelength of light from at least a portion of the light emitting element; and a color filter layer disposed on the wavelength conversion layer and including: a color filter corresponding to the emission region; and a first light blocking portion corresponding to the light blocking area and the non-display area. The first light blocking portion has a transmittance of about 80% or more with respect to light having a wavelength of about 1000 nm or more.
Description
technical field [0001] The present disclosure relates to a display device and a tiled display device including the display device. Background technique [0002] As the information society advances, demands for display devices for displaying images are increasing in various forms. For example, display devices have been applied to various types of electronic devices such as smart phones, digital cameras, notebook computers, navigation systems, and smart televisions. The display device may be a flat panel display device such as a liquid crystal display device, a field emission display device, and an organic light emitting display device. Among flat panel display devices, the light-emitting display device may include a display panel, each pixel of the display panel may include a light-emitting element capable of emitting light, and thus the light-emitting display device may display without a backlight unit providing light to the display panel image. [0003] When a display de...
