Abstract
A large multicolor display apparatus displays pictures and animations of high quality with multiple colors. The apparatus is used for advertisement and information purposes. The apparatus comprises unit blocks, which are divided into a plurality of sections. In each of the sections, there is arranged a multicolor display element having a rotary color display member. The color of each unit block is determined by the multicolor display elements disposed in the unit block. Each of the unit blocks, therefore, can display multiple colors, to improve the quality of images displayed on the apparatus. Since the multicolor display elements can be prepared in small sizes, they operate at high speed to display animations and make the apparatus thinner and lighter.
