Problems solved by technology

[0005] Therefore, the inventors of the present invention have studied the application of the transverse electric field method, which is advantageous in terms of viewing angle and image quality, to a transflective liquid crystal device. When the reflective layer is provided in the sub-pixel, good display cannot be obtained in both reflective display and transmissive display even when the multi-gap method is adopted.

no. 1 Embodiment approach

[0031] Hereinafter, a liquid crystal device according to a first embodiment of the present invention will be described with reference to the drawings. The liquid crystal device of this embodiment is one of the lateral electric field methods in which images are displayed by applying an electric field in the direction of the substrate surface (lateral electric field) to the liquid crystal to control alignment. ) mode of the liquid crystal device.

[0032] In addition, the liquid crystal device of this embodiment is a color liquid crystal device provided with a color filter on a substrate, and one pixel is constituted by three sub-pixels that output light of each color of R (red), G (green), and B (blue). . Therefore, a display area constituting the smallest unit constituting a display is referred to as a "sub-pixel area", and a display area composed of a set of (R, G, B) sub-pixels is referred to as a "pixel area".

no. 2 Embodiment approach

[0069] Second, refer to Figure 5 A second embodiment of the present invention will be described. Figure 5 (a) is a partial cross-sectional configuration diagram of a liquid crystal device 201 according to the first configuration example of the present embodiment; Figure 5 (b) is a partial sectional configuration diagram of a liquid crystal device 202 according to a second configuration example of the same embodiment. The liquid crystal devices 201 and 202 of this embodiment both have the same basic configuration as the liquid crystal device 100 of the first embodiment, except that the second interlayer insulating film 13 provided between the pixel electrode 9 and the common electrode 19, It is formed to have different film thicknesses in the sub-pixel area. Thus, in Figure 5 in, right and from Figure 1 to Figure 4 Components that are the same as those of the liquid crystal device 100 shown in FIG.

[0070] First of all, yes Figure 5 The liquid crystal device 201 of...

no. 3 Embodiment approach

[0087] Second, refer to Image 6 A third embodiment of the present invention will be described. Image 6 , is a diagram showing a schematic planar configuration of the sub-pixel region of the liquid crystal device 300 of the present embodiment.

[0088] The liquid crystal device 300 of this embodiment adopts the Image 6 The pixel electrode 39 having the configuration shown in 2 is used instead of the pixel electrode 9 in the liquid crystal device 100 of the first embodiment, and the other configurations are the same as those of the liquid crystal device 100 . Thus, in Image 6 From and to Figure 1 to Figure 4 The same components are denoted by the same symbols, and their detailed descriptions are omitted.

[0089] exist Image 6 The pixel electrode 39 shown in , has a plurality of (ten in the figure) strip-shaped electrodes 39c, and each strip-shaped electrode 39c is electrically connected to each other and is electrically connected to the TFT. The pixel electrode 39 o...

Abstract

The invention provides the liquid crystal equipment. The half-transmitting reflection-type crystal equipment has the pixel electric pole (9) and common electric pole (19) at the side of liquid crystal layer (50) of TFT array base plate (10), and in one pixel area the equipment installs the reflection display area (R) and transmission display area (T). The relative dielectric constant of insulation film between pixel electric pole (9) and common electric pole (19) is less than that of insulation film in transmission display area (T).

Description

technical field [0001] The present invention relates to a liquid crystal device and electronic equipment. Background technique [0002] As a kind of form of liquid crystal device, the mode (hereinafter referred to as transverse electric field mode.) that makes the electric field of substrate plane direction act on liquid crystal layer and carry out the mode of alignment control of liquid crystal molecule is known; It is called an IPS (In-Plane Switching, in-plane switching) method, an FFS (Fringe-Field Switching, fringe field switching) method, and the like. For example, Patent Document 1 below discloses a transverse electric field system (FFS system) liquid crystal device in which comb-shaped electrodes are provided on upper and lower layers sandwiching a dielectric film therebetween. [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 11-202356 [0004] However, transflective liquid crystal devices are used in the display units of portable electronic ...
