1. An organic light emitting device comprising:

a first component including a first plurality of layers, the first plurality of layers including a thin film transistor layer deposited on a surface of a first substrate, an emitting component layer deposited on the thin film transistor layer, and a passivation layer deposited on the emitting component layer;

a second component including a second plurality of layers, the second plurality of layers deposited on a surface of a second substrate without an adhesive contacting the surface of the second substrate and at least one of the second plurality of layers, the second plurality of layers including a touch sensor deposited on the second substrate and a color filter layer deposited on the touch sensor or the second plurality of layers including the color filter layer deposited on the second substrate and the touch sensor deposited on the color filter layer; and

an adhesion layer between the first component and the second component, the adhesion layer coupling together the first component and the second component.

2. The organic light emitting device of claim 1 , wherein the first component further comprises a first barrier layer deposited between the first substrate and the thin film transistor layer, and wherein the second component further comprises a second barrier layer deposited between the second substrate and the touch sensor.

3. The organic light emitting device of claim 1 , wherein the emitting component layer of the first component includes a bank layer that overlaps a light-shielding layer included in the color filter layer of the second component.
