Problems solved by technology

[0012] However, in a display panel having a display area having a unique shape, for example, a display panel in which the edge of the display area is formed in a curved shape, there is a problem that the edge area of ​​the display area formed in a curved shape looks stepped, or the display is unexpected. Outer colors, display quality degraded

Embodiment approach 1

[0056] figure 1 It is a diagram showing the liquid crystal display panel 1 in which the upper right region in the figure is shielded from light by the light shielding portion 3 as part of the edge region in the display region 2 .

[0057] Such as figure 1 As shown in (a), a plurality of pixels 11 are included in the display area 2, and each pixel 11 includes a red sub-pixel 10R that transmits red light at a predetermined transmittance, and a green sub-pixel 10R that transmits green light at a predetermined transmittance. The sub-pixel 10G, and the blue sub-pixel 10B that transmits blue light at a predetermined transmittance. Therefore, in each pixel 11 , a predetermined color can be displayed by appropriately adjusting the transmittance of each color light from the red sub-pixel 10R, the green sub-pixel 10G, and the blue sub-pixel 10B.

[0058] In this embodiment, the case where one pixel 11 includes three sub-pixels 10R, 10G, and 10B is taken as an example for description...

Embodiment approach 2

[0114] Below, based on Image 6 with Figure 7 Embodiment 2 of the present invention will be described. The difference between the liquid crystal display panel 40 of the present embodiment and the first embodiment is that only the sub-pixels 41R, 41G, 41B, and 43R are adjusted among the pixels 42 , 44 , and 46 passing through the ideal line that is a curved boundary line. , 43G, 43B, 45R, 45G, 45B openings in the second direction perpendicular to the longitudinal direction (first direction), that is, the width of the left-right direction in the figure (the length of the above-mentioned longitudinal direction (first direction) remains is fixed), other content is the same as that described in Embodiment 1. For convenience of description, members having the same functions as those shown in the drawings of Embodiment 1 are assigned the same reference numerals, and description thereof will be omitted.

Embodiment approach 3

[0134] Below, based on Figure 8 with Figure 9 Embodiment 3 of the present invention will be described. The liquid crystal display panel 50 of this embodiment differs from Embodiments 1 and 2 in that the sub-pixel light-shielding portions of the light-shielding portion 3 are set in accordance with the pixel 52 and 54 where an ideal line that is a curved boundary line passes, for example. A grid shape with a plurality of openings is formed, and the size of the openings of the sub-pixels 51R, 51G, 51B, 53R, 53G, and 53B, that is, the size of the sub-pixel light-shielding portion of the light-shielding portion 3 is adjusted by changing the density of the openings, Other contents are the same as those described in Embodiments 1 and 2. For convenience of description, members having the same functions as those shown in the drawings of Embodiments 1 and 2 are assigned the same reference numerals, and description thereof will be omitted.

Abstract

To prevent the display quality from being degraded as a result of (i) a boundary portion of an edge region of the display region being visibly in the shape of stairs and / or (ii) emitted light having an unintended color, a display panel includes a light-shielding section including, for each pixel (5) through which a curved boundary line (ideal line) extends, sub-pixel light-shielding sections (3a)each overlapping a corresponding one of a red sub-pixel (4R), a green sub-pixel (4G), and a blue sub-pixel (4B).

Description

[0001] This application is a divisional application, the application number of the original application is 201780041611.2, the international application number is PCT / JP2017 / 024279, the application date is July 03, 2017, and the invention name is "display panel". technical field [0002] The present invention relates to a display panel such as a liquid crystal display panel or an organic EL display panel. Background technique [0003] In recent years, there has been a strong demand for display devices with high designability, and liquid crystal displays that have a smooth box shape and curve-shaped edges of the display area of ​​the display panel have been actively developed. Display panels such as panels or organic EL display panels. [0004] Figure 13 It is a diagram showing an example of a liquid crystal display panel having a generally rectangular display area and a liquid crystal display panel having a uniquely shaped display area. [0005] Figure 13 (a) is a figure ...
