Problems solved by technology
However, considering the misalignment between the color filter CF and the light-shielding film BM, the width b between adjacent illumination areas BA (the width of the light-shielding film BM) must be enlarged, making it difficult to achieve a high aperture ratio or high definition.

Embodiment Construction
[0075] Hereinafter, embodiments of the liquid crystal display device of the present invention will be described in detail with reference to the accompanying drawings of the embodiments. Figure 1A-Figure 1C It is a schematic diagram of one side substrate illustrating the structure of the first embodiment of the liquid crystal display device of the present invention, Figure 1A Represents a planar view around a pixel, Figure 1B means along Figure 1A The profile of the line A-A', Figure 1C means along Figure 1A Sectional view of line B-B'. This liquid crystal display device has a pair of substrates (one substrate and the other substrate) suitably used as insulating substrates such as a glass plate, and is configured by sandwiching liquid crystal between the two substrates. A cell gap, which is a gap between two substrates, is controlled by a spacer member. In addition, in Figure 1A-Figure 1C Only the substrate SUB 1 forming the multicolor color filter CF is shown in t...

The present invention provides a liquid crystal display device which exhibits improved color reproducibility, high definition and a high numerical aperture by minimizing a change of a total area of color filter non-forming regions even when a position of a color filter is displaced. A color filter forming region and the color filter non-forming regions are formed within a lighting region which isvisible to a viewer in the inside of one pixel. Further, in the inside of one pixel, a first side of the lighting region includes both of the color filter forming region and the color filter non-forming region, a second side of the lighting region which faces the first side in an opposed manner includes both of the color filter forming region and the color filter non-forming region, the first sideassumes the color filter non-forming region at a region which faces the color filter forming region of the second side in an opposed manner, and the second side assumes the color filter non-forming region at a region which faces the color filter forming region of the first side in an opposed manner.
Description
technical field [0001] The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device having a color filter forming region and a color filter non-forming region in an illuminated region visually recognizable by an observer in one pixel. Background technique [0002] Liquid crystal display devices are widely used as display devices for electronic equipment such as notebook computers, word processors, electronic notebooks, mobile phones, and camera-camera recorders due to their thin profile, light weight, and low power consumption. Unlike cathode ray tubes and plasma devices, this liquid crystal display device does not emit light itself, but displays images and the like by controlling the amount of light incident from the outside. In addition, since there are multicolor color filters as light control elements, it is possible to display multicolor color images. The most common liquid crystal display device currently u...
