Description

Window manufacturing device and window manufacturing method using the device The present invention relates to a window manufacturing apparatus and a window manufacturing method, and more specifically, to a window manufacturing apparatus for manufacturing a glass window including a partially slimmed area and a window manufacturing method using the apparatus. Various types of electronic devices are used to provide video information, and recently, electronic devices including flexible display panels that can be folded or bent are being developed. Unlike rigid electronic devices, flexible electronic devices can change their shape in various ways, such as by folding, rolling, or bending, and thus have the characteristic of being portable regardless of the screen size on which an image is displayed. Such flexible electronic devices require a window to protect the display panel without hindering folding or bending movements. Accordingly, there is a need to develop a method for manufacturing a window and a manufacturing apparatus that have excellent surface features that do not affect display quality while having good folding characteristics.
