Abstract
Abstract A liquid crystal display device includes laminated plural electrical field effect type liquid crystal layers with light-transmitting electrically insulating layers inserted therein, and liquid crystal injection holes for forming the columns for supporting the insulation layers and the liquid crystal layers. The structure of the liquid crystal display device is changed in the manner that the columns are striped so as to increase the width thereof and the liquid crystal injection holes are rod-shaped so as to increase the section width thereof. Accordingly, the gap of the liquid crystal layers is maintained and the etching time for dissolution layers is considerably reduced, thereby improving the structural quality of the liquid crystal display device and obtaining a uniformly displayed image.
