Problems solved by technology

In addition, even if the hollow portion is kept in a vacuum state, the substrate is pressed by the atmospheric pressure and deformed, thereby easily causing unevenness in the gap between the substrates (interval unevenness).

Embodiment Construction

[0017] Hereinafter, the configuration of the first embodiment will be described with reference to the drawings.

[0018] exist Figure 1 to Figure 3 Among them, 11 is a liquid crystal panel as a liquid crystal display element, and this liquid crystal panel 11 is, for example, a transmissive active matrix type that transmits planar light from an unillustrated backlight (back light) disposed on the back side and displays an image. LCD panel.

[0019] That is, the liquid crystal panel 11 has a structure in which an array substrate 12, which is a quadrangular active matrix substrate (first) substrate, and a quadrangular opposing substrate 13, which is a (second) substrate. 13 as the display side are arranged to face each other with a predetermined gap (cell gap), and bonded by, for example, a quadrangular frame-shaped sealing portion 14, and a liquid crystal layer composed of a liquid crystal material LC is filled inside the sealing portion 14 15. On the display side of the arra...

Abstract

According to one embodiment, a liquid crystal panel includes substrates opposed to each other and paired. The liquid crystal panel includes a liquid crystal layer interposed between the substrates. The liquid crystal panel includes a sealed portion that includes bending corner portions at positions spaced from the outer edges of the substrates, and surrounds the periphery of the liquid crystal layer and bonds the substrates together. The liquid crystal panel includes main spacers that are interposed between the substrates at the position of the liquid crystal layer and hold the gap between the substrates. The liquid crystal panel includes auxiliary spacers that are interposed between the substrates to fill the portions between the outer side portions of the corner portions of the sealed portion and the outer edge sides of the substrates and hold the gap between the substrates.

Description

[0001] This application is based on Japanese patent application 2013-15918 (application date: July 30, 2013), and enjoys the priority benefits from this application. This application incorporates this application in its entirety by reference. technical field [0002] Embodiments of the present invention relate to a liquid crystal display element having a curved corner and a sealing portion that surrounds a liquid crystal layer and bonds substrates together, and a method for manufacturing the same. Background technique [0003] Conventionally, a liquid crystal panel (LCD), which is a commonly used liquid crystal display element, is bonded with a liquid crystal layer sandwiched between a pair of substrates, which are made of, for example, glass or the like and each have an electrode, via a sealing portion as an adhesive. An electric field is applied to the liquid crystal layer to control the transmission / blocking of light by the liquid crystal layer to display an image. [00...
