Abstract

Disclosed are a cover window and a foldable display device including the cover window. The present invention provides a cover window comprising: a first region having a first stiffness; a second region having a second stiffness greater than the first stiffness; and nano Particles, the nanoparticles are located in the boundary between the first region and the second region.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a cover window having improved reliability and a foldable display device including the same. Background technique [0002] With the development of information technology and mobile communication technology, display devices capable of displaying visual images have also been developed. Flat panel display devices such as liquid crystal display (LCD) devices and organic light emitting display (OLED) devices are developed and used. [0003] In general, an LCD device includes a liquid crystal panel including upper and lower substrates and a liquid crystal layer between the upper and lower substrates. The liquid crystal layer is driven by an electric field induced between the pixel electrode and the common electrode to display images. [0004] An OLED device includes an organic light emitting diode including an anode, a cathode, and an organic light emitting layer between the anode...
