A mobile computing device has a touch sensitive display screen for displaying an image including a pictorial representation of a location. Cross sections of the pole portion layers and a gap layer parallel to the top surface of a substrate are of the same shapes. Thus, the reflective-transmissive type LCD apparatus may prevent occurrence of the afterimage, and may enhance a contrast ratio thereof when operated in a transmissive mode. A button can be carried by the sleeve, and is depressable to force the pin away from the outer tube, allowing the inner tube to slide.
