Abstract: A light-emitting element used for display devices and illuminating devices has been formed on a flat substrate, and therefore, when the size of such devices is increased, manufacturing apparatuses also have to be enlarged. Also, a problem involved has been that even a failure of one light-emitting element causes the entire device to fail, making improvement of production yield difficult. To solve the above problems, in the present invention, light-emitting elements are formed as linear elements, and the linear elements are combined to form a plane light-emitting device. This enables the light-emitting device to be produced by selecting only linear light-emitting elements of good quality, and enlargement of apparatuses and enhancement of production yield can be expected.
