Embodiment 1

[0078] (i) Polarizer

[0079] Three commercially available polarizing plates (manufactured by Nitto Denko, product name "CWQ1463VCUHC") were prepared, and they were set as the first polarizing plate (polarizer), the second polarizing plate (polarizer) and the third polarizing plate (polarizer). polarizer).

[0080] (ii) Cover plate

[0081] Using a commercially available methacrylic resin sheet (manufactured by Nitto Jushi Kogyo Co., Ltd., product name "Flat N-885", thickness 1.0 mm), a part corresponding to the display area of ​​the liquid crystal cell described below was punched out. into the opening.

[0082] (iii) Liquid crystal unit

[0083] The liquid crystal panel was taken out from Century's product name "plus one" (IPS mode), and the optical film attached to the upper and lower sides of the liquid crystal cell was removed, and the optical film removal surface was washed. The liquid crystal cell obtained in this way was used.

[0084] (iv) Production of liquid cry...

Abstract

A liquid crystal display device is provided which has a step between a display screen and the topmost surface, in which said step is not readily apparent, and which can achieve a bright display. Thisliquid crystal display device is provided with: a liquid crystal cell; a first polarizer arranged on the back side of the liquid crystal cell; a second polarizer arranged on the visible side of the liquid crystal cell; a cover sheet arranged on the visible side of the second polarizer and having an opening in a position corresponding to the display region of the liquid crystal cell; and a third polarizer arranged on the visible side of the cover sheet so as to cover the opening. The opening in the cover sheet is filled with an adhesive.

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] Liquid crystal display devices are used in a wide range of applications represented by televisions, smartphones, computer monitors, and digital cameras, and the applications tend to expand further. As a result, liquid crystal display devices have taken the form of being embedded in various structures depending on the application of the liquid crystal display device. As a specific example of such an application, it can be mentioned: the operation information screen of the railway vehicle (for example, the next stop guidance display of the passenger car), the display of various instruments or navigation systems arranged on the instrument panel or console of the automobile, etc. Various instruments in the cockpit of the department and the aircraft, and monitors installed in hospitals, guard rooms or combat command posts. In this form, due to the protection an...
