Problems solved by technology

Therefore, there is a problem that the aperture ratio is lowered, and due to the overlapping of the common electrode and the common line, a step is generated at the position of the upper electrode overlapping the common line in plan view, and the alignment of the liquid crystal molecules is disturbed at the stepped portion.
Therefore, an opaque common line for interconnecting the common electrodes is not formed for each pixel

[0045] Next, an FFS-mode liquid crystal display panel 10A using an array substrate according to a first embodiment of the present invention will be described using FIGS. 1 to 4 . Such as Figure 1B , image 3 and Figure 4A As shown, in the liquid crystal display panel 10A, the liquid crystal layer LC is interposed between the array substrate AR and the color filter substrate CF. The liquid crystal layer LC is sealed by the sealing material 11 so that the liquid crystal layer LC can be prevented from leaking outward from between the array substrate AR and the color filter substrate CF, and the thickness of the liquid crystal layer LC is uniformly maintained by column spacers (not shown). Polarizers (not shown) are formed on the rear surface of the array substrate AR and on the front surface of the color filter substrate CF. Light is emitted from the rear surface side of the array substrate AR to the liquid crystal display panel 10A through a backlight (not shown). The liqu...

Abstract

Disclosed herein is a liquid crystal display panel of a transverse electric field system, including: a liquid crystal layer; and a pair of substrates configured to be so disposed as to be opposed to each other and sandwich the liquid crystal layer. In the liquid crystal display panel, a first electrode and a second electrode for applying an electric field to the liquid crystal layer and an alignment film are formed in a plurality of pixel areas that form a display area in one of the pair of substrates, a planarization insulating film is formed on a surface of at least one of the first electrode and the second electrode and across an entire surface of the pixel areas, and the alignment film is formed on a surface of the planarization insulating film.

Description

technical field [0001] The present invention relates to a liquid crystal display panel of a transverse electric field system, and in particular to a liquid crystal display panel of an in-plane switching (IPS) mode and a fringe field switching (FFS) mode, in which the surface of an array substrate is flattened, and Occurrence of burn-in, display unevenness, and flicker is suppressed. Background technique [0002] Compared with cathode ray tubes (CRTs), liquid crystal display panels have the characteristics of light weight, thinner thickness and lower power consumption, so they are used as display units of various electronic devices. The liquid crystal display panel displays images by changing the orientation of liquid crystal molecules aligned in a predetermined direction by an electric field and thereby changing the amount of light passing through the liquid crystal layer. [0003] Methods of applying an electric field to a liquid crystal layer of a liquid crystal display p...
