A display apparatus includes a first substrate, a first shielding layer, a first optical film, a second substrate, and a display medium. The first shielding layer is located on the first substrate and has a first alignment pattern. The first optical film is located on the first substrate. The first optical film has a second alignment pattern on a side edge of the first optical film. The first alignment pattern and the second alignment pattern are overlapped with each other. The second substrate is located opposite to the first substrate. The display medium is sandwiched between the first substrate and the second substrate.
