Liquid crystal display device, method of making the same, and electronic apparatus

Abstract

A liquid crystal display device includes a first substrate, a second substrate opposed to the first substrate, a liquid crystal layer between the first and second substrates, a plurality of seals arranged in a sealing area located around a display area in which an image is displayed through the liquid crystal layer, and two sealing portions each connecting ends of the seals to seal the space. The seals extend along the sealing area on the first substrate. The adjacent seals are disposed with a space therebetween in the direction from the center of the display area to the periphery thereof. The seals join the first substrate to the second substrate.
