    • A surface light source device includes a light source body having an internal space. A partition wall is disposed in the internal space of the light source body to divide the internal space into a plurality of discharge spaces. The partition wall has end portions that make contact with inner surface of the light source body. The partition wall has a throughhole, through which the discharge spaces are connected to each other. The light source body includes a voltage applying part that applies a voltage to the discharge space to generate plasma in the discharge space. A barrier is disposed adjacent to the throughhole to restrict a flow of the plasma generated from a discharge gas through the throughhole. The barrier screens the throughhole to restrict the flow of the plasma through the throughhole. Therefore, uniformity of luminance of the surface light source device is improved.
    • 面光源装置包括具有内部空间的光源体。 分隔壁设置在光源体的内部空间中,以将内部空间分成多个放电空间。 分隔壁具有与光源体的内表面接触的端部。 分隔壁具有通孔,排放空间通过该通孔相互连接。 光源体包括向放电空间施加电压以在放电空间中产生等离子体的电压施加部。 屏障靠近通孔设置,以限制从放电气体通过通孔产生的等离子体的流动。 屏障屏蔽通孔以限制等离子体通过通孔的流动。 因此,提高了表面光源装置的亮度的均匀性。
