Display device and method of manufacturing the same

A method of manufacturing a display device, the method comprising:

• forming an element substrate by forming a driving element and a light emitting element on a first substrate, the first substrate including a first display area and a first non-display area adjacent to the first display area;
• forming color filters on a second substrate including a second display area corresponding to the first display area, a second non-display area corresponding to the first non-display area and adjacent to the second display area, and a cutting area extending from the second non-display area;
• forming a first opening in the color filters to expose the second substrate in the second non-display area;
• forming a second opening in the color filters to expose the second substrate in the cutting area such that the second opening is spaced apart from the first opening;
• forming a refractive layer on the color filters to fill the first opening and the second opening;
• attaching the second substrate to the element substrate such that the refractive layer faces the driving element and the light emitting element;
• and
• cutting a portion between the first opening and the second opening.
