Abstract

The present invention pertains to: a display panel provided with a first substrate, a second substrate, a liquid crystal layer that is held between the substrates, a first orientation film that is provided to a surface facing the liquid crystal layer of the first substrate, and a second orientation film that is provided to a surface facing the liquid crystal layer of the second substrate; and a display apparatus provided with the display panel. This display panel is configured such that all directors of a plurality of liquid crystal compositions constituting the liquid crystal layer are substantially perpendicular to the first orientation film and the second orientation film when no voltage is applied, a liquid crystal layer included in each of a plurality of unit pixels arranged in a matrix along row and column directions has a single orientation state, the director of the liquid crystal composition positioned at the center of a first unit pixel which is one of the unit pixels is reverse to the director of the liquid crystal composition positioned at the center of a second unit pixel which is present in the same row or column as that of the first unit pixel.

Description

technical field

[0001] The invention relates to a display panel and a display device. Background technique

[0002] Liquid crystal display devices are widely used not only in small and medium-sized display devices such as portable electronic devices, but also in display devices used in televisions, digital signage, and the like. The penetration rate of large display devices is increasing year by year, and in particular, the proportion of display devices having a size of 50 inches or more is increasing. However, considering the ease of installation, it is not preferable to blindly increase the size of the display device, and it is considered that the size of the display device for at least personal use is about 75 inches at most.

[0003] On the other hand, the demand for high-definition display devices is still high, so the number of pixels of the display devices is still increasing. Specifically, from the previous full high-definition FHD (1,920Γ—1,080, 8,294,400 dots) to ...
