Abstract
A display device includes a first substrate and a barrier layer disposed on the first substrate. A thin film transistor is on the barrier layer. An organic light emitting element is connected to the thin film transistor. The barrier layer includes a metal including at least one of Al, Ag, Cu, Mo, Cr, or Ta.
Claims20
A display device comprising:
- a first substrate;
- a barrier layer disposed on the first substrate;
- a thin film transistor on the barrier layer;
- and
- an organic light emitting element connected to the thin film transistor,
- wherein the barrier layer comprises a metal including at least one of Al, Ag, Cu, Mo, Cr, or Ta.

A method of manufacturing a display device, the method comprising:
- forming a barrier layer on a first substrate;
- forming a thin film transistor on the barrier layer;
- forming an organic light emitting element on the thin film transistor;
- and
- forming a thin film encapsulation layer on the organic light emitting element,
- wherein forming of the barrier layer on the first substrate comprises:
- depositing a metal;
- and
- substantially simultaneously depositing a metal and an oxygen gas.
6 more elements
A display device comprising:
- a substrate;
- an auxiliary buffer layer disposed on the substrate;
- a barrier layer disposed on the auxiliary buffer layer;
- a buffer layer disposed on the barrier layer;
- a thin film transistor disposed on the barrier layer;
- and
- a light emitting element positioned above the thin film transistor, wherein the light emitting element overlap the thin film transistor along a direction orthogonal to an upper surface of the substrate,
- wherein the barrier layer comprises an oxide of Al, Ag, Cu, Mo, Cr, or Ta, and
