Aperture fluorescent lamp, surface illuminator, manufacturing methods thereof, liquid crystal display device, and electronic device

摘要

A relatively small-diameter aperture fluorescent lamp is manufactured easily with high yield and at low cost. An aperture portion is formed in a manner that a thread-like member is inserted into a glass tube having an ultraviolet ray reflection layer and a phosphor layer formed on its inner surface, the glass tube is bent in a predetermined shape by using a bending jig, the thread-like member is pressed to the phosphor layer formed in a predetermined region in the bending member side of the glass tube while both ends thereof are pulled tight, the thread-like member is reciprocated, and phosphor of the phosphor layer in this region is exfoliated.
