Abstract
A display control circuit of a display unit is divided such that circuit portions and connecting means susceptible to noise are arranged in the display unit, while circuit portions and connecting means other than the circuit portions and connecting means susceptible to noise are placed away from the display unit through an extension cable. Due to this, the display unit can be made thinner and noises can be prevented from entering the circuit portions and connecting means arranged in the display unit. Further, the display apparatus may have a movement mechanism for making the display unit stand up. In this case, two guide grooves are formed at the sides of an intermediate case of the display unit housing. Due to this, the intermediate case can be made thinner, matching the thickness of the display unit.
