摘要： The process for the production of a spacered substrate for use in a self-emitting display, provided by the present invention, comprises the steps of exposing a photosensitive glass to light while masking a portion to form a spacer on a surface of the photosensitive glass, to form a latent image corresponding to an exposed portion, crystallizing the exposed portion having the latent image, removing a crystallized exposed portion by an etching treatment, and thereby forming a spacer of non-exposed photosensitive glass on a glass substrate. According to the present invention, there is provided a spacered substrate for use in a self-emitting display, in which the spacer has high accuracy and high heat resistance and the roughening of the substrate surface is not easily caused.
