Regarding.

This type of display device has a light passing section formed at either the left or right end of each display cell, a shutter for opening and closing the light passing section of the parenthesis for each display cell, and a shutter moving mechanism placed behind the display panel. By moving the shutter to the left or right, the shutter is moved within the display cell.By moving the shutter to either the left or right end, the light passage section is opened or closed, and predetermined information is displayed.

However, in this conventional oak display device, the positions of all the light passage parts with respect to the display cells are the same, so in order to change the display information, all the light passage parts are closed once, and then the predetermined light passage parts are closed. Therefore, each time the display information is changed, the shutter moving mechanism must be reciprocated, which has the drawback that it takes time to change the display information.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display device in which display information can be changed by simply moving a shutter moving mechanism from one end to the other end once.

In order to achieve the above object, the present invention divides each light passage into two groups, such as a group located in an odd numbered row (or column) of a matrix and a group located in an even numbered row (or column). The light passing portions of one group are arranged close to one side of the display cell, and the light passing portions of the other group are arranged close to the other side of the display cell.

In this way, by moving the shutter once in one direction, it is possible to change the display using the light passing section of one solution to the display using the light passing section of the other group, and the shutter f! in the opposite direction once! By moving 8, it is possible to change the display using the light passing section of the -b rating instead of the display using the light passing section of the other group, and it is possible to change the display contents in a short time.
