Abstract
A flat type fluorescent lamp that serves as an illuminating unit and a back light of a large sized liquid crystal panel. The flat type fluorescent lamp includes a first substrate, a second substrate, a first electrode formed on the first substrate, the first electrode including a plurality of protrusions, a phosphor layer formed on the second substrate, a second electrode formed on the phosphor layer, and supports selectively formed between the first substrate and the second substrate. A method for manufacturing a flat type fluorescent lamp comprising the steps of forming a first electrode with protrusions at different intervals on a first substrate, forming a barrier layer over an entire surface of the first substrate including the first electrode, forming a phosphor layer on a second substrate, forming a second electrode on the phosphor layer, selectively forming supports between the first substrate and the second substrate and bonding the first substrate to the second substrate.
