Problems solved by technology

[0007] Pixels displaying green and blue can fully display various object colors even if the brightness is lowered, but pixels displaying red cannot display part of the object colors if the brightness is lowered
In this way, if the brightness is reduced by increasing the number of primary colors used, the display quality of red is reduced, and red becomes jet-black red (that is, dark red).

Embodiment approach 1

[0061] figure 1 The liquid crystal display device 100 in this embodiment is shown. Such as figure 1 As shown, the liquid crystal display device 100 has a plurality of pixels arranged in a matrix including a plurality of rows and a plurality of columns. The plurality of pixels include a red pixel R that displays red, a green pixel G that displays green, a blue pixel B that displays blue, and a yellow pixel Y that displays yellow. One picture element P, which is the minimum unit for performing color display, is defined by four consecutive pixels in the row direction. In each picture element P, four pixels are arranged in the order of red pixel R, green pixel G, blue pixel B, and yellow pixel Y from left to right.

[0062] Such as figure 1 As shown, in the liquid crystal display device 100 , the area of ​​the red pixel R and the blue pixel B is larger than the area of ​​the green pixel G and the yellow pixel Y. That is, in the present embodiment, each pixel row of a plura...

Embodiment approach 2

[0086] refer to Figure 5 with Image 6 , the liquid crystal display device 200 in this embodiment will be described. In the liquid crystal display device 200, such as Figure 5 with Image 6 As shown, the areas of the red pixel R, the green pixel G and the blue pixel B are relatively large, and the area of ​​the yellow pixel Y is relatively small. That is, the red pixel R, the green pixel G, and the blue pixel B are large pixels, and the yellow pixel Y is a small pixel.

[0087] In each picture element P, 4 pixels are sequentially arranged with red pixel R, green pixel G, blue pixel B, and yellow pixel Y from left to right. Therefore, along the row direction, large pixels, large pixels, large pixels, and small pixels are repeatedly arranged in the order.

[0088] In the liquid crystal display device 200 , the positions of the bent portions 13 c in the column direction of any two adjacent signal lines 13 in the row direction among the plurality of signal lines 13 are diff...

Embodiment approach 3

[0092] refer to Figure 7 with Figure 8 , the liquid crystal display device 300 in this embodiment will be described. In the liquid crystal display device 300, such as Figure 7 with Figure 8 As shown, each picture element P is defined by a red pixel R, a green pixel G and a blue pixel B. Therefore, the liquid crystal display device 300 is not a multi-primary-color liquid crystal display device, but a three-primary-color liquid crystal display device. Also, the areas of the red pixel R, the green pixel G, and the blue pixel B are equal to each other. That is, in the liquid crystal display device 300 , the area of ​​the pixels is uniform, and there is no mixture of large pixels and small pixels.

[0093] In the liquid crystal display device 300 , the positions of the bent portions 13 c in the column direction of any two adjacent signal lines 13 in the row direction among the plurality of signal lines 13 are different from each other. Therefore, the area of ​​the region ...

Abstract

Provided is a liquid crystal display device, wherein each of a plurality of signal lines (13) comprises, in a region corresponding to each of a plurality of pixel rows, a first straight line section (13a) that overlaps with only one pixel electrode (11) of two pixel electrodes (11) adjacent to the signal line (13), a second straight line section (13b) that overlaps with only the other pixel electrode (11), and a bent section (13c) that connects the first straight line section (13a) and the second straight line section (13b) to each other, and the positions in the column direction of the bent sections (13c) of arbitrarily defined two signal lines (13) that are adjacent along the row direction among the plurality of signal lines (13) are different from each other. Consequently, the source-to-drain capacitance (Csd) can be easily adjusted pixel by pixel.

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] Currently, liquid crystal display devices are used in various applications. In a general liquid crystal display device, one picture element is constituted by three pixels displaying three primary colors of light, red, green, and blue, thereby enabling color display. [0003] However, conventional liquid crystal display devices have a problem that the range of displayable colors (referred to as "color reproduction range") is narrow. If the color reproduction range is narrow, part of object colors (colors of various objects existing in nature; see Non-Patent Document 1) cannot be displayed. Therefore, in order to expand the color reproduction range of the liquid crystal display device, a method of increasing the number of primary colors used for display has been proposed. [0004] For example, in Patent Document 1, such as Figure 18 As shown, there is disc...
