摘要:
A liquid crystal display device includes pixels, arranged in a two-dimensional matrix on a substrate, for displaying an image, and several types of transistors, fabricated monolithically on the substrate for driving the respective pixels. One transistor in each pixel is juxtaposed on a periphery section of an adjacent pixel. By sharing such sections between adjacent pixels the fabrication of the transistors is simplified with the area occupied by each transistor and the pixel size reduced.

An elevator information device is disclosed. The elevator information device has displays located in each hall of a building, each of which can display the service state of the elevator (information on arrival of a car, number of passengers in the car, floors at which the car is about to stop, waiting time, position of the car) by means of pictures and characters, whereby waiting passengers can easily understand the condition of the elevator. As a result, the waiting passengers do not feed uncomfortable due to confusion, impatience or distrustfulness. Consequently, the waiting passengers can be guided smoothly.
