Abstract
A display apparatus capable of reducing a leakage current and effectively transmitting an electrical signal to a plurality of opposite electrodes includes a pixel definition layer including a first opening, a spacer including a second opening, wherein at least a portion of a body portion of the spacer is disposed in the first opening to cover a side surface of the pixel defining layer.
Claims18
A display apparatus comprising:
- a substrate;
- a pixel electrode disposed over the substrate;
- a pixel definition layer including a first opening exposing at least a portion of the pixel electrode, the exposed portion of the pixel electrode including an emission area and a connection area;
- a spacer disposed over the pixel definition layer and including a second opening exposing at least a portion of the pixel electrode;
- an emission layer arranged in the emission area;
- and
- an opposite electrode disposed over the emission layer and covering at least a portion of the spacer and the pixel definition layer,
- wherein at least a portion of a body portion of the spacer is disposed in the first opening to cover a side surface of the pixel definition layer, and
- wherein, in an area other than the connection area, the opposite electrode disposed over the emission layer is disconnected from the opposite electrode disposed on an upper surface of the spacer.

A display apparatus comprising:
- a first pixel electrode and a second pixel electrode arranged apart from each other over a substrate;
- a pixel definition layer including a (1-1)th opening exposing at least a portion of the first pixel electrode to define a first emission area and a first connection area, and a (1-2)th opening exposing at least a portion of the second pixel electrode to define a second emission area and a second connection area;
- a spacer disposed over the pixel definition layer and including a (2-1)th opening exposing at least a portion of the first pixel electrode and a (2-2)th opening exposing at least a portion of the second pixel electrode;
- a first emission layer arranged in the first emission area and a second emission layer arranged in the second emission area;
- and
- an opposing electrode disposed over the first emission layer and the second emission layer and at least partially covering the pixel definition layer and the spacer,
- wherein at least a portion of a body portion of the spacer is arranged in the (1-1)th opening and the (1-2)th opening, an inner surface of the pixel definition layer defining the (1-1)th opening and the (1-2)th opening forms an obtuse angle with an upper surface of the substrate, and an inner surface of the spacer defining the (2-1)th opening and the (2-2)th opening forms an acute angle with the upper surface of the substrate, and
- wherein, in an area other than the first connection area and the second connection area, the opposite electrode disposed over the first pixel electrode and the opposite electrode disposed over the second pixel electrode are disconnected.
