Problems solved by technology

Also, in this case, the adhesiveness of the sealing material and the alignment film is not sufficient, so it cannot be completely sealed, and it becomes a cause of leakage of the liquid crystal material of the liquid crystal layer.

Embodiment approach 1

[0090] figure 1 and 2 An overall schematic diagram of the liquid crystal display device 10 according to Embodiment 1 is shown. in addition, image 3 An enlarged cross-sectional view showing the vicinity of the sealing region SL of the liquid crystal display device 10 is shown. and, Figure 4 and 5 The top views of the array substrate 20 and the opposite substrate 30 are shown respectively.

[0091] The liquid crystal display device 10 includes an array substrate 20 (first substrate) and an opposing substrate 30 (second substrate) arranged to face each other. On the substrate main body 20S of the array substrate 20, the first metal (first wiring) including the gate line 21, the gate insulating film 22, and the source line 23 (refer to Figure 6 ) second metal (second wiring); passivation film 24; planarization film 25; third metal including pixel electrodes (not shown); The detailed configuration of the array substrate 20 will be described later. In addition, on the su...

Deformed example 1～3

[0125] In Embodiment 1, it was explained that the grooves 27 are provided in double, and only the groove base metal 27a corresponding to the outermost groove 27 is connected to the transmission pad 28, and the groove base metal 27a of the lower layer of the groove 27 on the inner peripheral side is not formed. The floating state is electrically connected to other wiring, but in the case where the grooves 27 are provided in multiple rows, each groove base metal 27 corresponding to all the grooves 27 may be connected to the transmission pad 28, and conversely, all the grooves may be connected to each other. Base metal 27a is in a suspended state.

[0126] For example, as Modification 1 Figure 12 and 13 As shown, the transfer pad lead-out line 28a may be formed so as to extend to the vicinity of the lower layer of the inner groove 27, and the transfer pad lead-out line 28a may be in contact with the groove base metal 27a of the lower layer of the outer groove 27 through the tra...

Deformed example 4

[0129] In Embodiment 1, the transmission pad 28 is provided with a common potential by the transmission bus line (not shown) provided on the outer periphery thereof, but the transmission bus line may not be provided on the outer periphery of the transmission pad 28, and as in Modification 4, a common potential may be provided. Figure 18 As shown, the groove base metal 27a is made to function as a transmission bus. In this case, the groove base metal 27a is connected to an external connection terminal (not shown) by the common potential input line 28d, and is electrically connected to the transfer pads 28 by the transfer pad lead-out lines 28a. Also, the common potential supplied from the external connection terminal is transmitted to the transfer pad 28 through the trench base metal 27 a. Since the function of the transmission bus is given to the groove base metal 27a, it is possible to omit providing the transmission bus independently on the outer periphery of the transmissi...

Abstract

Grooves (27) are formed on first wiring lines (21, 23a) of a first substrate so as to continuously extend along an outer peripheral edge section of the substrate and so as to transverse the first wiring lines (21, 23a). Groove backing metal (27a) is provided on the same layer as a second wiring line (23) in the layer underneath at least the areas in which the grooves (27) overlap with the first wiring lines (21, 23a) in planar view.

Description

technical field [0001] The present invention relates to a display device such as a liquid crystal display device, and particularly relates to a structure around a groove provided in a frame region in order to control the application region of an alignment film. Background technique [0002] Liquid crystal display devices can be thinned and have low power consumption, so they are widely used as displays for OA (office automation) equipment such as televisions and personal computers, mobile phones, and portable information equipment such as PDA (Personal Digital Assistant). [0003] A liquid crystal display device includes: a liquid crystal display panel; and a backlight unit mounted on the rear side of the liquid crystal display panel. A liquid crystal display panel has a structure in which an array substrate including switching elements such as thin film transistors and an opposing substrate disposed opposite to the array substrate are bonded together with a sealing material...
