Abstract:
A display apparatus includes: a first substrate on which a plurality of light-emitting devices are arranged; a plurality of light controllers arranged above the first substrate and corresponding to the plurality of light-emitting devices; and a plurality of banks between the plurality of light controllers, wherein each bank of the plurality of banks includes a black pigment and a scattering agent. Because the display apparatus according to an embodiment includes a bank including a black pigment and a scattering agent, color mixing between pixels is prevented or reduced, and light efficiency is increased.
