A line-illuminating device which is resistant to shrinkage problems caused by repetition of heating and cooling includes a white casing made of polycarbonate or the like, a light guide made of an acrylic resin or the like and accommodated in the casing such that the light-emitting surface thereof is exposed, and light-emitting elements (for example, light-emitting diodes) as a light source provided on both ends of the casing so as to abut against the end surfaces of the light guide without a gap. The casing is divided into two portions in the longitudinal direction, and a gap is formed between the two divided portions. With this gap, even if the light guide shrinks due to repetition of heating and cooling, the divided portions can effectively shrink together with the light guide via the gap, and the abutting state between the end surface of the light guide and the light-emitting element can be maintained.

A substrate with a transparent condcutive film is provided, which has a high work function and an excellent surface smoothness as well as a reduced specific resistance to thereby ensure a reduced power consumption and enhanced display quality. An ITO film is formed on a glass substrate by an ion plating method by using an ITO sintered compact with an SnO content of 4 to 6 wt %. The ITO film obtained as above has a surface having a work function of 4.9 to 5.5 eV, a surface roughness of 1 to 10 nm, and a specific resistance of 1.6&times;10 &OHgr;&middot;cm or less. An organic EL device using the substrate is provided, in which an organic multilayer film (hole transport layer , light-emitting layer , and electron transport layer ) is laminated on the surface of the ITO film , and further a metal thin film layer is laminated on the surface of the organic multilayer film.
