Abstract
An LCD is integrated with the cover glass of a wrist watch radio paging receiver which indicates the time data with a dial plate and hands, and a message is displayed on the cover glass by controlling this LCD. In this message display, the parts of the characters indicating the message are made transparent and the remaining parts intercept light. In this manner, message display is made possible by the difference in light transmissivity.
