A keys-integrated LCD panel includes a first conductor arranged on one face of a transistor substrate and a second conductor arranged on one face of a color filter substrate facing toward the transistor substrate. The second conductor meets the first conductor without contacting with the first conductor, and a key district is formed at the position at where the second conductor meets the first conductor. When the key district is touched, the first and the second conductor electrically contact with each other and the signal level at one of the first and the second conductor will change. A controller is provided for detecting any change in the signal level at one of the first and the second conductor. When a change in the signal level is detected, the controller outputs a key signal corresponding to the touched key district. |
