A display apparatus includes a first substrate provided with a closed container, two types of charged particles held in the closed container and having mutually different charge polarities and a substantially identical color, and first, second and third electrodes for generating an electric field in the closed container, with the third electrode being disposed on the first substrate. The display apparatus alternately executes a first display operation and a second display operation, wherein in the first display operation, the charged particles create a first distribution on a first electrode side by changing a voltage applied to the second electrode or the third electrode after a first reset operation in which the charged particles create a second distribution on a second electrode side and on a third electrode side by applying a first voltage to the second electrode and to the third electrode. In the second display operation, the charged particles create a third distribution on the first electrode side by ch
