Display device having light blocking part in non-display area and tiled display device including the same

A tiled display device comprising:

• display devices each having a display area and a coupling area between the display areas, each of the display areas having emission areas and a light blocking area;
• and
• a bonding member bonding the display devices in the coupling area,
• wherein each of the display devices comprises:
• a substrate;
• a thin film transistor layer on the substrate and comprising thin film transistors;
• a light emitting element layer on the thin film transistor layer and comprising light emitting elements;
• a wavelength conversion layer on the light emitting element layer to convert a peak wavelength of light provided from at least some of the light emitting elements;
• and
• a color filter layer on the wavelength conversion layer, the color filter layer comprising:
• color filters in each of the emission areas;
• a first light blocking part in the light blocking area;
• and
• a second light blocking part in the coupling area.
