SURFACE LIGHT SOURCE DEVICE FOR PREVENTING DEFORMATION OF SUBSTRATES BY STRESS COMPENSATION, FABRICATING METHOD THEREOF, LCD HAVING THE SAME

摘要

PURPOSE: A surface light source device is provided to compensate stress generated on a lower substrate while forming barrier walls on the lower substrate by that generated on the lower substrate while forming a reflection layer thereon, thereby preventing the deformation of the lower substrate formed with the barriers and the reflection layer. CONSTITUTION: A surface light source device includes an upper substrate(3), and a lower substrate(5) corresponding to the upper substrate. A plurality of barrier walls(10) are formed between the upper and lower substrates for forming discharging spaces(11) between the upper and lower substrates. The lower substrate is formed with a reflecting layer(15), and insides of the discharging spaces are respectively formed with fluorescent layers(20). As predetermined electric fields are applied into the discharging spaces from electrodes, plasma discharge is induced into the discharge spaces, generating UV rays. By the UV rays, fluorescent substances is excited from the fluorescent layer, and visible rays are generated from the fluorescent layer. The electrodes surrounds both outer surfaces of the upper or lower substrate.
