Abstract

A lift pin driving device and a flat panel display (FPD) manufacturing apparatus having the device are provided. The lift pin driving device can precisely move a plurality of lift pins using one motor, thus realizing a simple lift pin driving structure and a simple motor control structure. This allows a space below a chamber body of the manufacturing apparatus to be configured in a variety of ways, thus reducing the cost of equipment and the production cost of products.
