Abstract

A display apparatus includes a flexible first substrate, a first lower barrier layer, a thin film transistor layer, a first planarization layer, a first barrier layer, a first electrode, a second electrode, and a light emitting layer. In the display apparatus, a first through portion penetrating the first planarization layer is formed on the first planarization layer, a second through portion penetrating the first barrier layer and at least partially connected to the first through portion is formed on the first barrier layer, part of the first electrode fills the first through portion and the second through portion, and an area of the second through portion is equal to or greater than 30% of an area of the first electrode in plan view of the main surface of the first substrate.
