Abstract
In forming four liquid crystal panels on a glass substrate, layout is so made that peripheral driving circuit areas of the respective panels are opposed to each other. With this layout, the peripheral driving circuit areas, which are prone to be affected by particles, are prevented from existing in regions close to the perimeter of the glass substrate. This allows liquid crystal panels to be produced at a high yield, as well as enables efficient use of the glass substrate.
