In other words, the metal film 7c2 constituting the conductive anti-reflection layer 7c imparts conductivity to the lead wiring 7, and the low-reflective metal oxide film 7cl reduces the reflectance of the lead wiring 7 itself. As will be described in more detail, the conductivity of the lead wiring 7 is improved by laminating the metal film 7c2 on the transparent conductive layer 7d, and further, a low-reflective metal oxide film 7ci is formed on one side of the metal film 7c2. Compared with the case of only the metal film 7c2, the reflectance of the lead wiring 7 is reduced. Further, in order to reduce the reflectance of the lead wiring 7 on the display surface 1a side, it is necessary to form the low-reflection metal oxide film 7ci on the side closest to the substrate ίο-.

Further, the film thickness of the low-reflective metal oxide film 7 (1) is preferably in the range of 3 〇 nm or more to 80 nm or less, and more preferably in the range of 4 〇 nm or more to 6 〇 nm or less. Further, the film thickness of the transparent conductive layer 7d is preferably in the range of 100 nm or more to 300 nm or less, and more preferably in the range of i 5 〇 nm or more to 250 nm or less. When the film thickness of each of the layers 7c 1 , 7c 2 , and 7 d of the wiring 7 is in the above range, the reflectance of the lead wires 7 can be in the range of 3% or more to 5% or less, and the electric resistance of the lead wires 7 itself can be made 4 Ω or less, preferably 1.5 Ω or more and 3 Ω or less. Further, 'the example in which the conductive anti-reflection layer 7c is formed by two layers is shown in FIG. 5', but the present invention is not limited thereto, and In this case, the conductive anti-reflection layer 7c can be formed of a low-reflection metal film such as a NiCu-based alloy or a Ni-based alloy. The metal film has both high conductivity and low reflectivity, and is hostile. The film can improve the conductivity of the lead wires 7 and reduce the reflectance. Further, the lead wires 6 can be formed in the same manner as the lead wires 7, or can be formed only of a transparent conductive material such as ITO. Since the line length is shorter than the lead line 7, the voltage drop is smaller than the lead line 7, and therefore it can be formed only of a transparent conductive material such as IT0. Therefore, in the present embodiment, the lead lines 6 and 7 are taken out. All or part of the laminated structure of the conductive anti-reflection layer and the transparent conductive layer may be formed. As described above, the liquid crystal display device 1 according to the above-described embodiment has a connection formed on the first substrate 1 The formation position of the film 67 formed on the wiring board is set to be close to the position of the driving IC 5?, and the end of the wiring pattern 66 & in the FPC. 66 is formed at a position close to the driving 1C 50. Since the gap between the drive and the acf film is reduced as compared with the conventional liquid crystal display device, the exposed portion of the connection wiring 6b can be reduced, and the connection wiring 6b is hardly exposed to air or the like. In the division, the electrolytic corrosion of the connection wiring 6b can be prevented, and a highly reliable liquid crystal display device can be formed. Further, since the electrolytic corrosion preventing resin 80 is filled in the gap between the driving 1C 50 and the ACF film 67, the connection is increased. The effect of preventing the electrolytic corrosion can be further improved by the protective effect of the wiring 6b. In the liquid crystal display device 1 of the present embodiment, the sealing material 4 经由 formed by each of the conductive conductive resins is placed on the first substrate. The lead-out side of one side is connected to the transparent electrode 25 on the side of the second substrate 2, and the transparent electrode 25 can be led out to the ith substrate 1 via the lead-out wiring 7 at 85941 -16 - 1307439. One side side ' Thus, the drive IC 5〇 can be grouped into one. In addition, the wiring pattern of the FPC provided in the liquid crystal display device of the above-described embodiment is not limited to the pattern shape shown in FIG. 6 or FIG. 7, and may have another shape, and the wiring of the FPC at this time is formed in the vicinity of the drive 1C. One end of the pattern (the end connected to the side on the drive 1C via the ACF film) may be used. (Effect of the Invention) As described in detail above, the liquid crystal display device of the present invention can prevent the connection wiring formed on the substrate for driving and the flexible printed wiring board attached to the substrate or the other substrate. The electrolyzed rot shoes can constitute a highly reliable liquid crystal display device.
