Problems solved by technology

[0005] Although a touch screen panel is applied to a flexible display device, the window layer at the outermost side of the flexible display device has a flexible property, and thus, its surface may be easily damaged due to contact with a hand or a touch pen.
May reduce the flexibility of the display device when the window layer is made of a rigid material to prevent or reduce damage to the surface

Abstract

Disclosed herein is a flexible display device including a display panel displaying an image, a touch screen panel on the display panel, and a window substrate covering the touch screen panel. The window substrate includes: a flexible base layer including a first surface facing an outside and a second surface facing the display panel in an opposite direction to the first surface; and a coating layer having hardness higher than that of the base layer and having a plurality of coating tiles arranged on the first surface of the base layer thereof, each coating tile being spaced from adjacent ones of the coating tiles.

Description

technical field [0001] The described techniques generally relate to display devices. Background technique [0002] A display device is a device that visually displays data. Generally, a display device (usually one of output devices of a computer) is a device that enables a user to directly see the result processed by the computer through his / her eyes by displaying the result on a screen. Types of display devices include cathode ray tubes (CRTs), liquid crystal displays (LCDs), organic light emitting diode displays (OLED displays), electrophoretic displays (EPDs), and the like. With recent developments in the field of display devices, display devices are currently not limited to functions as output devices of computers, but have been variously applied to application fields such as television receivers, portable communication devices, wearable electronic devices, and the like. [0003] Among display devices, liquid crystal displays, organic light emitting diode displays, ele...
