Problems solved by technology

[0011] However, when the electrodes are formed in the shape of a ㄑ, compared with the conventional IPS mode liquid crystal display device having rectangular electrodes, the shape of the electrodes is complicated and it is difficult to ensure the aperture ratio in one pixel.
Therefore, it is difficult to use electrodes with a ㄑ-shaped structure in liquid crystal display devices that require high-definition image quality.

Abstract

To ensure an aperture ratio and enhance display characteristic as viewed from a wide angle side. There is provided a liquid crystal display device having a liquid crystal interposed between a pair of substrates, in which an electric field parallel to a surface of each of the substrates is applied to the liquid crystal, thereby changing a display state. The liquid crystal display device comprises a retardation film arranged at a side opposite to the liquid crystal of one substrate of the substrates, a first polarizing plate which is arranged at a side opposite to the substrate of the retardation film and which has a transmission axis parallel to an alignment direction of the liquid crystal, and a second polarizing plate which is arranged at a side opposite to the liquid crystal of the other substrate and which has a transmission axis orthogonal to the alignment direction of the liquid crystal.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] In a liquid crystal display device using a twisted nematic (Twisted Nematic) liquid crystal, a narrow viewing angle has conventionally been regarded as a problem. In order to solve this problem, a liquid crystal display device in an IPS (In-plane Switching) mode that changes the display state by applying an electric field parallel to the substrate surface (hereinafter referred to as a transverse electric field) to the liquid crystal has been proposed ( Refer to Patent Document 1). However, even in such an IPS mode liquid crystal display device, when viewed from the wide-angle side, light leakage occurs in the case of black display, and blue or yellow color sticking occurs in the case of white display. Deterioration of characteristics. [0003] As a technical solution to the problem of such an IPS mode liquid crystal display device, it has been proposed to prevent...
