Abstract

Claims (36)

1. A data processing device comprising:

a display portion being foldable,

wherein when the display portion is folded to face inward, a part of the display portion which does not face a user of the data processing device is configured to stop displaying,

wherein the display portion comprises:

a first substrate having flexibility;

a first adhesive layer over the first substrate;

a transistor over the first adhesive layer;

an insulating layer over the transistor;

a lower electrode of a light-emitting element over the insulating layer;

a partition having a region overlapping with an end portion of the lower electrode;

a layer comprising a light-emitting organic compound, the layer overlapping with the lower electrode in a region where the partition is not provided;

an upper electrode of the light-emitting element over the layer;

a coloring layer over the upper electrode;

a second adhesive layer over the coloring layer; and

a second substrate having flexibility over the second adhesive layer,

wherein the light-emitting element is configured to emit light to an outside of the second substrate through the coloring layer,

wherein a photodiode is provided below the light-emitting element so as not to overlap with the light-emitting element and a channel formation region of the transistor, and

wherein the photodiode is located at a position where light from above the second substrate is incident without passing through the coloring layer and the partition.

2. The data processing device according to claim 1 , wherein one of a source and a drain of the transistor is electrically connected to the lower electrode through a conductive layer.

3. The data processing device according to claim 1 , wherein the channel formation region of the transistor has a part overlapping with the lower electrode.

4. A data processing device comprising:

a display portion being foldable,

wherein when the display portion is folded to face inward, a part of the display portion which does not face a user of the data processing device is configured to stop displaying,

wherein the display portion comprises:

a first substrate having flexibility;

a first adhesive layer over the first substrate;

a transistor over the first adhesive layer;

a light-emitting element over the transistor;

a coloring layer over the light-emitting element;

a second adhesive layer over the coloring layer; and

a second substrate having flexibility over the second adhesive layer,

wherein the light-emitting element is configured to emit light to an outside of the second substrate through the coloring layer, and

wherein a photodiode is provided below the light-emitting element so as not to overlap with the light-emitting element and a channel formation region of the transistor.

5. The data processing device according to claim 4 , wherein one of a source and a drain of the transistor is electrically connected to a lower electrode of the light-emitting element through a conductive layer.

6. The data processing device according to claim 4 , wherein the channel formation region of the transistor has a part overlapping with a lower electrode of the light-emitting element.

7. The data processing device according to claim 4 , wherein the photodiode is located at a position where light from above the second substrate is incident without passing through the coloring layer.
