Abstract

An electronic apparatus includes a display unit including a display panel and a display circuit board connected to the display panel. An input sensing unit includes a touch panel which includes an active area and a peripheral area adjacent to the active area and includes sensor patterns disposed in the active area, and a touch circuit board connected to the peripheral area of the touch panel. A polarizing film is disposed on the input sensing unit and is configured to polarize incident light. A step-difference compensation member is disposed between the polarizing film and the input sensing unit and includes a main portion overlapping the active area and a plurality of slit portions disposed between the main portion and the touch circuit board.
