## Abstract

The disclosure provides a flexible device. The flexible display device includes a flexible substrate and a planarized layer. A thickness of the planarized layer is in a range from 0.5 μm to 200 μm. A thickness ratio of the thickness of the planarized layer to a thickness of the flexible substrate is in a range from 0.025 to 20.

## Claims

### Claim 1
