[0048] by Figure 1 to Figure 11 The first embodiment of the present invention will be described. In the present embodiment, the liquid crystal panel (display device, display panel) 11 included in the liquid crystal display device 10 having a position input function is exemplified. In addition, X-axis, Y-axis, and Z-axis are shown in a part of each drawing, and each axis direction is drawn so that it may become a direction shown in each drawing. In addition, image 3 , Image 6 as well as Figure 7 The upper side of etc. is the front side, and the lower side of these figures is the back side.

[0049] Such as figure 1 As shown, the liquid crystal display device 10 has a rectangular shape as a whole, includes a liquid crystal panel 11 capable of displaying images, and includes a backlight device that is an external light source that is arranged on the back side of the liquid crystal panel 11 and irradiates the liquid crystal panel 11 with light for display (Lighting device) etc. ...

[0083] according to Figure 12 to Figure 14 The second embodiment of the present invention will be described. In this second embodiment, the structure of the insulating films 116, 119, 120, 122, 125, the overlapping portion 130, and the like is changed. In addition, overlapping descriptions of the same structure, action, and effect as those of the first embodiment described above are omitted.

[0084] Such as Picture 12 As shown, for the array substrate 111b according to this embodiment, the entire area of ​​each insulating film 116, 119, 120, 122, 125 that overlaps the mounting area of ​​the driver and the flexible substrate in the non-display area NAA It is removed by opening together. Therefore, in the insulating film non-arrangement regions NLA1 to NLA3, in addition to the non-display area that overlaps with each terminal portion (including the input terminal portion 128), it also includes each terminal portion including the area between the terminal portions. The outer a...

[0088] according to Figure 15 or Figure 16 The third embodiment of the present invention will be described. In this third embodiment, the structure of the insulating films 216, 219, 220, 222, 225, the overlapping portion 230, and the like are changed from the first embodiment described above. In addition, overlapping descriptions of the same structure, action, and effect as those of the first embodiment are omitted.

[0089] Such as Figure 15 as well as Figure 16 As shown, in the array substrate 211b according to the present embodiment, in the insulating films 216, 219, 220, 222, and 225, the frame-shaped area surrounding the display area AA in the non-display area NAA is removed by opening. The regions formed by the openings respectively become insulating film non-arrangement areas (including the insulating film non-arrangement areas NLA1 to NLA3). The non-arrangement area of ​​the insulating film is in each insulating film 216, 219, 220, 222, 225 in a planar shape similar ...

Abstract

An array substrate (11b) is provided with: a glass substrate (GS) which is divided into a display area (AA) and a non-display area (NAA); a gate insulation film (16) and a first interlayer insulationfilm (19) which, in the non-display area (NAA), comprise a gate insulation film non-arrangement area (NLA1) and first interlayer insulation film non-arrangement area (NLA2) that have an opening in a portion thereof; a gate insulation film rising portion (16a) and a first interlayer insulation film rising portion (19a) which rise from the boundary position between the gate insulation film non-arrangement area (NLA1) and the first interlayer insulation film non-arrangement area (NLA2) and form a slope inclined with respect to the surface of the glass substrate (GS); and an overlapping portion (30) which, in the form of straddling from the area of the gate insulation film non-arrangement area (NLA1) and the first interlayer insulation film non-arrangement area (NLA2) to the area of the gate insulation film rising portion (16a) and the first interlayer insulation film rising portion (19a), overlaps with at least some of these.

Description

Technical field [0001] The invention relates to a display substrate and a display device. Background technique [0002] As an example of a liquid crystal panel used in a conventional liquid crystal display device, a liquid crystal panel described in Patent Document 1 below is known. For the active element array substrate constituting the liquid crystal panel described in Patent Document 1, convex portions are provided at the ends of the interlayer insulating film and between adjacent mounting terminals, so that even if the interlayer insulating film is thickly formed In the case, the resist residue in the subsequent process will also be eliminated. [0003] Prior art literature [0004] Patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 11-24101 [0006] Technical problem to be solved by the present invention [0007] In the active element array substrate described in Patent Document 1, the ends of the interlayer insulating film in the interlayer insulating fil...
