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.

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.
