Abstract
Disclosed herein is a light source device. The light source device includes a front transparent substrate, a rear substrate, a plurality of partitions, and fluorescent material. The rear substrate is configured to face the front transparent substrate with a discharge space disposed therebetween. The partitions are arranged between the front transparent substrate and the rear substrate to divide the discharge space into a plurality of discharge channels. The fluorescent material is applied on the inside of the discharge space. Meanwhile, the partitions are formed such that the ratio of the radius of curvature R of each partition to the width W of the partition, that is, R/W, ranges from 0.1 to 4.
