Abstract: A window member including a base substrate and a light shielding layer including a first light shielding pattern disposed in a first area of the base substrate and a second light shielding pattern disposed in a second area of the base substrate while being spaced apart from the first light shielding pattern and providing a signal transmission area at an inner side thereof. The second light shielding pattern includes an edge having a plurality of curved portions on a plane. This arrangement reduces an area of the light shielding pattern adjacent to the signal transmission area of the window member.

Abstract: A pad printing device for printing a window of a display device includes a pad to transfer ink to the window. The pad includes a printing portion to transfer the ink to the window by being pressed against the window and a body portion disposed on the printing portion and to apply a pressure to the printing portion. A hardness of the printing portion is less than a hardness of the body portion, and a sidewall of a portion of the pad where the printing portion contacts the body portion is substantially perpendicular to the window.

Abstract: Provided is a method of thermoforming a molding material to have a bent portion and a flat portion extending from the bent portion. The method includes: placing the molding material on a bending mold, the bending mold having a curved surface; and forming the bent portion of the molding material by heating a portion of the molding material at least to a fluidization temperature such that the portion of the molding material bends due to the weight of the flat portion of the molding material to form the bent portion according to a shape of the bending mold.

Abstract: Systems and methods are provided for manufacturing a window from a transparent member. Forming the window may include forming of a groove by irradiating first laser light and removing a portion of a transparent member by irradiating second laser light focused at a depth of the groove. The first laser light may be emitted from a first laser generator and may be irradiated along an edge of a first area defined in a second surface of the transparent member. A second laser light may be focused to the depth of the groove, and thus a portion of the transparent member may be cut. The second laser light may be emitted by a second laser generator, and a focus of the second laser light may be located within the transparent member.
