The device includes a photo mask having a central light-transmitting region and a peripheral light-transmitting region disposed at a periphery of the central light-transmitting region; and an exposure device right opposite to the photo mask. Wherein, light emitted from the exposure device is irradiated to a negative photoresist material after passing through the photo mask, the light intensity passing through the peripheral light-transmitting region is less than the light intensity passing through the central light-transmitting region. A spacer is also disclosed. Only one exposure process is required to realize the spacer having a convex-shaped cross section. The process is simple and the manufacturing cost is low. At the same time, a flatness of the convex shoulder of the spacer having a convex-shaped cross section is adjustable, which can satisfy the requirement for manufacturing spacers having different specifications.Type: GrantFiled: September 25, 2015Date of Patent: April 17, 2018Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventors: Huan Liu, Zui Wang, Jinbo Guo, Shih-hsun Lo
