An LCD(Liquid Crystal Display) is provided to properly utilize a marginal space by forming a button switch at a region where a pattern is not formed on a thin film transistor substrate of a liquid crystal panel. A color filter substrate(110) is bonded with one region of a thin film transistor substrate(120), and has a size smaller than that of the thin film transistor. A button switch is formed at the other region of the thin film transistor substrate. The button switch includes a first switch pattern(124) and a second switch pattern(126) spaced apart from each other at the other region of the thin film transistor, and a dome button having a lower outer circumferential surface placed on the first switch pattern and an upper convex surface placed on the second switch pattern and having elasticity and conductivity.
