Embodiment approach 1

[0048] figure 1 It is a schematic cross-sectional view of the liquid crystal display of Embodiment 1, showing TFTs and their surroundings in the display region.

[0049] The liquid crystal display of the present embodiment is an active matrix drive type and a transmissive type liquid crystal display, and is an FFS type liquid crystal display which is one type of horizontal alignment mode. Such as figure 1As shown, the liquid crystal display of this embodiment includes a liquid crystal panel 1, a backlight (not shown) disposed behind the liquid crystal panel 1, a control unit (not shown) for driving and controlling the liquid crystal panel 1 and the backlight, and a The liquid crystal panel 1 is connected to a flexible substrate (not shown) of the control unit.

[0050] The liquid crystal panel 1 includes a display area for displaying images, and a plurality of pixels are arranged in a matrix in the display area. In addition, each pixel may be composed of sub-pixels of a p...

Embodiment approach 2

[0094] This embodiment is substantially the same as Embodiment 1 except that the structure near the end of the counter electrode is different. Therefore, in this embodiment, the characteristics unique to this embodiment will be mainly described, and the description of the contents overlapping with Embodiment 1 will be omitted. In addition, the same code|symbol is attached|subjected to the member (including the part) which has the same or the same function in this embodiment and Embodiment 1, and the description of the member is abbreviate|omitted in this embodiment.

Abstract

The purpose of the present invention is to provide a liquid crystal display in which moisture resistance and resist coating properties are improved, and disturbances in the alignment of liquid crystal molecules is suppressed. This liquid crystal display is provided with an organic insulating film (18), a transparent electrode (19) on the organic insulating film (18), and an interlayer insulating film (20) on the transparent electrode (19). The transparent electrode (19) has a plasma-treated surface. The organic insulating film (18) is cut from an end (19a) of the transparent electrode (19) in the vertical direction, and has a step section (18a) under the end (19a). The transparent electrode (19) does not protrude from the step section (18a) toward the side, and the height of the step section (18a) is set at 20 nm or less.

Description

technical field [0001] The present invention relates to liquid crystal displays. In more detail, it is related with the liquid crystal display of the fringe field switching (FFS: Fringe Field Switching) system suitable as 1 type of horizontal alignment mode. Background technique [0002] A liquid crystal display generally includes: a thin film transistor substrate (hereinafter also referred to as an array substrate) on which pixel electrodes and thin film transistors (TFT) are formed in a matrix; The counter substrate of the chip is a liquid crystal layer sandwiched between the array substrate and the counter substrate. Also, an image is generated by controlling the light transmittance by controlling the alignment of liquid crystal molecules in the liquid crystal layer on a pixel-by-pixel basis. [0003] Since liquid crystal displays are flat and lightweight, they are used in a wide variety of fields, from large display devices such as TVs to mobile phones and DSCs (Digita...
