Display device and method for manufacturing the same

A display device comprising:

• a first substrate;
• first to third sub-pixel electrodes adjacent to each other on the first substrate;
• a second substrate positioned opposite to the first substrate;
• a light-transmitting pattern on the second substrate and at least partially overlapping with the first sub-pixel electrode, the light-transmitting pattern including a first surface facing the first substrate and a second surface facing the second substrate;
• a wavelength conversion pattern on the second substrate and including a first surface facing the first substrate and a second surface facing the second substrate, the wavelength conversion pattern including a first wavelength conversion pattern at least partially overlapping with the second sub-pixel electrode and a second wavelength conversion pattern at least partially overlapping with the third sub-pixel electrode;
• a first black matrix filling a separation space between a side surface of the light-transmitting pattern and a side surface of the first wavelength conversion pattern and including a first surface facing the first substrate and a second surface facing the second substrate;
• and
• a planarization layer on the wavelength conversion pattern, the light-transmitting pattern, and the first black matrix,
• wherein the first surface of the first black matrix is wider than the second surface of the first black matrix, and
• wherein the first surface of the second wavelength conversion pattern is wider than the second surface of the second wavelength conversion pattern.
