Abstract
Proposed are a hybrid flexible cover window and a method of manufacturing the same. The hybrid flexible cover window includes a flat portion formed on a flat area of a flexible display and a folding portion which is formed in succession to the flat portion and formed in a folding area of the flexible display. The hybrid flexible cover window includes a substrate, a transparent polyimide layer formed on the glass substrate, and an adhesive buffer layer formed between the glass substrate and the TPI layer, in which the TPI layer has a UV cut-off wavelength of less than 380 nm.

A flexible hybrid cover window comprising a flat portion formed on a flat area of a flexible display panel and a folding portion, which is formed in succession to the flat portion and formed on a folding area of the flexible display, the flexible hybrid cover window comprising:
- a glass substrate;
- a transparent polyimide (TPI) layer formed on the glass substrate;
- an adhesive buffer layer formed between the glass substrate and the TPI layer,
- wherein the TPI layer has an ultraviolet cut-off wavelength of 380 nm or less,
- wherein the adhesive buffer layer is formed between the glass substrate and the TPI layer and formed on a side surface of the glass substrate in succession thereto,
- wherein the adhesive buffer layer is made of optical clear resin (OCR), and
- wherein the OCR adhesive buffer layer has a storage modulus in a range of 0.01 to 1 GPa.
