Abstract
A liquid crystal display device includes: a first substrate; a second substrate opposing the first substrate via a large number of columnar spacers therebetween, the columnar spacers being fixed on the first substrate; and a liquid crystal layer provided between the first substrate and the second substrate. The liquid crystal display device has a display area for displaying an image, and a non-display area adjacent to the display area. In the display area of the liquid crystal display device, a plurality of display electrodes that are used when applying a voltage across the liquid crystal layer are provided at an interval on one side of the first substrate that is closer to the liquid crystal layer, whereas in the non-display area, a plurality of peripheral electrodes are provided with substantially no interval therebetween on the side of the first substrate that is closer to the liquid crystal layer. Among the large number of columnar spacers in the liquid crystal display device, the columnar spacers in the display area are provided on the display electrodes while the columnar spacers that define a thickness of the liquid crystal layer in the non-display area are provided on the peripheral electrodes.
