Abstract: Island-shaped portions of colored layers each of which constitutes a part of a sub pixel are formed so as to be continuous with each other over the gap between adjacent pixels. The area of the island-shaped portion can be secured even when the size of the pixel is reduced to enhance the fineness, and peeling of the island-shaped portions at the formation time of a color filter layer which occurs in connection with miniaturization of the island-shaped portions can be suppressed, so that the yield can be improved while enhancing the display quality.

Abstract: An array substrate comprises a substrate, an underlayer including a plurality of switching elements formed on the substrate, a plurality of colored layers formed on the substrate and the switching elements, and a plurality of pixel electrodes provided on the colored layers and connected to the switching elements via contact holes formed in the colored layers, and a plurality of columnar spacers provided on the underlayer. The underlayer includes a plurality of same-structure portions extending perpendicular to the substrate. The columnar spacers are provided on the same-structure portions.

Abstract: A liquid crystal display device includes an array substrate, a counter-substrate, first pixel sections, second pixel sections, a liquid crystal layer, a color filter including first color layers, which form the first pixel sections, and second color layers which form the second pixel sections, and an undercoat insulation film including first light-transmissive inorganic parts, which form the first pixel sections and are set at such a film thickness that a wavelength at which a transmittance spectrum of the first pixel sections increases agrees with a wavelength at which a transmittance spectrum of the first color layers increases, and second light-transmissive inorganic parts which form the second pixel sections and are set at such a film thickness that a wavelength at which a transmittance spectrum of the second pixel sections increases agrees with a wavelength at which a transmittance spectrum of the second color layers increases.

Abstract: A color filter is disposed on a switching element array substrate. The color filter is composed of a plurality of kinds of color elements and an aperture. Two of the filter elements are overlapped at one end portion thereof. Each of the filter elements is covered with a pixel electrode. The pixel electrode is connected to the switching element through the aperture. This structure reduces electric coupling between the pixel electrode and the gate and signal lines. Optimum conditions among the overlapped width, and the aperture diameter and location are set to prevent the filter element from peeling off the array substrate so that the production yield can be significantly improved.
