1. A display device assembly, comprising:
a glass substrate; and
a display device disposed on the glass substrate, the display device including a first portion and a second portion having a light transmittance greater than the first portion,
wherein the display device includes at least one display pixel having a lower electrode, an emissive layer located on the lower electrode, and an upper electrode located on the emissive layer,
a lower portion of the glass substrate has a recess vertically corresponding to the second portion of the display device,
the at least one display pixel includes a first display pixel disposed at the first portion of the display device and a second display pixel disposed at the second portion of the display device,
the display device comprises an upper inorganic structure disposed on or over the first and second display pixels and a lower inorganic multilayer having at least one inorganic layer located on the glass substrate, the lower inorganic multilayer being disposed under or below the at least one display pixel, and
the lower inorganic multilayer and the upper inorganic structure make a direct contact with each other.
2. The display device assembly of claim 1 , further comprising an optical unit inserted into the recess.
3. The display device assembly of claim 1 , wherein the second portion of the display device is completely surrounded by the first portion of the display device in plan view.
4. The display device assembly of claim 1 , wherein the second portion of the display device is partially surrounded by the first portion of the display device in plan view.
5. The display device assembly of claim 1 , wherein the direct contact forms an inorganic-inorganic contact region completely surrounding the at least one display pixel in plan view.
6. The display device assembly of claim 1 , wherein
the lower inorganic multilayer has a hole vertically corresponding to the recess of the lower portion of the glass substrate.
7. The display device assembly of claim 6 , wherein the display device comprises an organic layer making a direct contact with an upper surface of the glass substrate at the second portion of the display device.
8. The display device assembly of claim 1 , wherein the lower inorganic multilayer expands to completely cover the recess of the glass substrate in plan view.
9. A display device assembly, comprising:
a glass substrate; and
a display device disposed on the glass substrate, the display device including a first portion and a second portion having a light transmittance greater than the first portion,
