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: A window for a display device that includes: a base substrate; a first coating layer disposed on a first surface of the base substrate; and a second coating layer disposed on a second surface that overlaps the first surface of the base substrate, wherein the base substrate further includes a vertical surface perpendicular to the first surface and the second surface, and the first coating layer overlaps the vertical surface. The impact resistance of the window is improved through the first coating layer covering the rear surface and the vertical surface of the base substrate.

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.
