Abstract
A planar light source including a first substrate, a second substrate, a sealant, first electrodes, sets of first dielectric patterns, a phosphor layer, and a discharge gas is provided. The second substrate is disposed above the first substrate. The sealant is disposed between the first and second substrates to form a cavity among the first substrate, the second substrate, and the sealant. The first electrodes are disposed on the first substrate, and each set of the first dielectric patterns has at least two first striped dielectric patterns. Each of the first striped dielectric patterns covers one of the first electrodes correspondingly. The edges of the top of each first striped dielectric pattern are raised in a peak shape. The phosphor layer is disposed on the first substrate and between the first striped dielectric patterns of each set of the first dielectric patterns. The discharge gas is injected into the cavity.
