A lithographic apparatus is disclosed. The apparatus includes an illumination system configured to condition a radiation beam, and a support constructed to support a patterning device. The patterning device is capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam. The apparatus also includes a substrate table constructed to hold a substrate, a projection system configured to project the patterned radiation beam onto a target portion of the substrate, a liquid supply system configured to at least partly fill a space between the projection system and the substrate with liquid, a seal member arranged to substantially contain the liquid within the space, and elements to control and/or compensate for evaporation of immersion liquid from the substrate.
