Abstract

A method of manufacturing a liquid crystal display element includes the steps of (a) forming a spacer having a uniform height on a glass substrate having formed thereon scanning lines, a black matrix, an insulating layer and an alignment layer in an area to which the black matrix is projected in a direction perpendicular to a substrate surface; (b) forming an adhesive layer on a transfer substrate; (c) pressing an upper surface of the spacer against the adhesive layer on the transfer substrate; and (d) selectively applying an adhesive only onto the upper surface of the spacer by the step (c). In the step (a), it is preferable that the spacer be formed so as to have a trapezoidal cross section with respect to a plane perpendicular to the lengthwise direction.
