no. 1 approach

[0024] figure 1 It is a plan view showing a schematic configuration of the display device 1 of the first embodiment. The display device 1 includes a display panel 2, a driver IC 3, and a backlight BL. The display panel 2 includes a first substrate SUB1 (array substrate), a second substrate SUB2 (counter substrate), and a liquid crystal layer LC. The liquid crystal layer LC is an example of a display function layer. exist figure 1 In an example, the size of the first substrate SUB1 is larger than the size of the second substrate SUB2. The 1st board|substrate SUB1 and the 2nd board|substrate SUB2 are bonded so that three sides may be aligned. The liquid crystal layer LC is sealed between the first substrate SUB1 and the second substrate SUB2.

[0025] The display panel 2 has, in a region where the first substrate SUB1 and the second substrate SUB2 overlap, a display region DA in which pixels PX for displaying images are formed, and a peripheral region SA around the display ...

no. 2 approach

[0079] A second embodiment will be described. The same reference numerals are assigned to the same elements as in the first embodiment. Structures and effects not particularly mentioned are the same as those of the first embodiment.

[0080] In the present embodiment, the relationship between the spacer for maintaining the cell thickness of the liquid crystal layer LC and the contact portion CP is disclosed as an example of a preferred arrangement form of the contact portion CP in the display area DA.

[0081] Figure 9 It is a cross-sectional view schematically showing an example of the spacer SS. The spacer SS is disposed between the first substrate SUB1 and the second substrate SUB2. As an example, the spacer SS is provided on the second substrate SUB2, and its front end is in contact with the first substrate SUB1. The spacer SS may be arranged between the above-mentioned overcoat layer 23 and the second alignment film 24 , or may be arranged under the second alignment ...

Abstract

The present invention provides a display device. The display device according to one embodiment includes: an insulating substrate; pixels arranged in a display area; scanning lines extending in a first direction in the display area; signal lines in the display area. extending along a second direction intersecting the first direction in the display area; a shielding wiring disposed between the insulating substrate and the scanning lines, facing the scanning lines and extending along the first direction; a pixel electrode, which is arranged in the pixel; and a first switching element, which includes a first semiconductor layer and is arranged in the display area. The first semiconductor layer is arranged between the scanning line and the shielding wiring, and has an intersection area crossing the scanning line. The shield wiring overlaps the intersection region in plan view, and is electrically connected to the scanning line through a contact portion.

Description

[0001] This application claims priority on the basis of Japanese Patent Application No. 2016-166895 for which it applied on August 29, 2016, The content is taken in in this specification by reference in its entirety. technical field [0002] The invention relates to a display device. Background technique [0003] For example, in a display device such as a liquid crystal display device, a switching element is provided for each pixel. In this switching element, when the channel region of the semiconductor layer is irradiated with light from a backlight or the like, leakage current occurs. Therefore, a technique of shielding the channel region of the semiconductor layer from light using a metal layer has been proposed. [0004] This metal layer is usually floating. Therefore, the metal wiring may be coupled to a signal line for supplying video signals and a pixel electrode, so that the potential of the pixel electrode may fluctuate due to the influence of the potential of the...
