1. An electronic device comprising:
a flexible display including a plurality of layers; and
a first housing structure and a second housing structure having the flexible display mounted thereon, the second housing structure coupled to the first housing structure and configured to slide in a first direction with respect to the first housing structure,
wherein the flexible display includes:
a first region; and
a second region extending from the first region in the first direction, wherein the second region has a higher flexibility,
wherein at least one of the plurality of layers has a first structure in the first region and has a second structure different from the first structure in the second region, and
wherein the first region of the flexible display is supported by the first housing structure and the second housing structure and is configured to remain flat, and at least part of the second region of the flexible display is configured to be curved and configured to be flat based on a sliding of the second housing structure, and
wherein the plurality of layers includes a display panel and a base film disposed in the first region and the second region and disposed under the display panel,
wherein the base film includes a flexible film having grooves in an area corresponding to the second region, and
wherein the display panel is disposed in the first region and the second region,
wherein the display panel includes a first plurality of light emitting elements that are disposed in the first region and a second plurality of light emitting elements that are disposed in the second region,
wherein the display panel further includes a thin film encapsulation layer disposed in the first region and the second region, and
wherein the thin film encapsulation layer in the second region divides the second plurality of light emitting elements into more divisions than the thin film encapsulation layer divides the first plurality of light emitting elements.
