PROBLEM TO BE SOLVED: To provide a wiring mutually connecting method which is of relatively inexpensive and is of simple and which enables a display having an increased visual field area in the liquid crystal planar panel display provided with plural liquid crystal display tiles which are arranged in a matrix and are fixed to tile carries. SOLUTION: Adjacent liquid crystal display tiles are electrically mutually connected in the inside of a device, thereby wiring escapes are obtained in pixels of the tiles. That is, an intertile interconnection 5 is formed, thereby a pixel wiring escape extending to surrounding of a tile display for horizontal address lines 6 and vertical address lines 7 is obtained. Then, even the center tile 8 is connected to adjacent tile wirings by the intertile interconnection in this manner and vertical pixel wirings 10 and horizontal pixel wirings can be both run.
