Embodiment Construction

[0048] Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3 .

[0049] In this embodiment mode, an example of application of the present invention to an active matrix type transflective liquid crystal display device using a TFT (Thin-Film Transistor thin film transistor) element as a switching element is shown. FIG. 1 is an exploded schematic perspective view showing the overall structure of a transflective liquid crystal display device according to this embodiment.

[0050] The liquid crystal display device 3 of the present embodiment includes a liquid crystal panel including a color filter substrate 80 and an element substrate (counter substrate) 90 as shown in FIG. 1 , and a backlight (not shown). The color element substrate 80 and the element substrate 90 are arranged to face each other with a liquid crystal layer (not shown) sandwiched between them, and the backlight is arranged on the side opposite to the viewing side of t...

Abstract

PROBLEM TO BE SOLVED: To provide a display device with an excellent image representation capability, which is capable of vividly reproducing colors present in nature.

Description

technical field [0001] The present invention relates to a display device and an electronic device, and particularly relates to a technique for improving the color reproducibility of a display. Background technique [0002] In color image display devices such as liquid crystal displays and organic electroluminescent (Electro-Luminescence, hereinafter referred to as EL) displays, generally, the additive color mixing of three primary colors of red (R), green (G) and blue (B) is used to generate Reproduce various colors. In this case, the reproducible color range (color reproduction range) in image display is limited to the area displayed as the sum of the color vectors of the three primary colors in the three-dimensional color space. In recent years, image expressiveness has been continuously improved along with the diversification of applications in image display devices, and for example, delicate color tone expression has been demanded. That is, expansion of the color repro...
