Abstract
A display apparatus includes a color filter with a color portion formed in at least one recess portion surrounded by partition walls on a substrate and a protective layer formed on the color portion and the partition walls. A thickness of the color portion is 20% to 80% of a thickness of the partition walls, and a thickness of a first protective layer formed on the partition walls is smaller than a thickness of a second protective layer formed on the color portion. In addition, a counter substrate faces the color filter, a liquid crystal layer exists between the color filter and the counter substrate, and a spacer is arranged on the first protective layer formed on the partition walls.
