1. A display apparatus, comprising:
a gate driving circuit configured to output a first light emission signal and a second light emission signal;
a first pixel circuit in a first display area of the display apparatus, the first pixel circuit including:
a first light emitting element configured to emit light based on the first light emission signal; and
a second light emitting element configured to emit light based on the second light emission signal;
a second pixel circuit in a second display area of the display apparatus, the second pixel circuit including:
a third light emitting element configured to emit light based on one of the first and second light emission signals; and
a fourth light emitting element configured to emit light based on the other of the first and second light emission signals;
a plurality of first lenses disposed on the first light emitting element and the second light emitting element in the first display area and disposed on one of the third and fourth light emitting elements in the second display area; and
at least one second lens disposed on the other of the third and fourth light emitting elements in the second display area,
wherein the first pixel circuit is configured to operate the first and second light emitting elements in a same mode,
wherein the second pixel circuit is configured to operate the third and fourth light emitting elements in different modes from each other,
wherein the first pixel circuit is configured to operate in a first mode with the first light emitting element emitting light and to operate in the first mode with the second light emitting element emitting light,
wherein the second pixel circuit is configured to operate in the first mode with the one of the third and fourth light emitting elements emitting light and to operate in a second mode with the other of the third and fourth light emitting elements emitting light, the second mode being different from the first mode,
wherein the first mode is a share mode using the plurality of first lenses, and
wherein the second mode is a privacy mode using the at least one second lens, the second display area having a narrower viewing angle in the privacy mode than in the share mode.
