That is, since the position of the foreign matter has nothing to do with the position of the switching element, when the foreign matter is arranged to straddle a plurality of switching elements, it is necessary to perform black dot defect on a plurality of dots, which increases the size of the black dot. , so that when seeking to further improve the display quality, it is difficult to cope with

Embodiment approach 1

[0039] Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 9 . In Embodiment 1, a normally black mode liquid crystal display device 10 using TFT 16 as a switching element is exemplified.

[0040] First, an outline of the configuration of the liquid crystal display device 10 will be described. A liquid crystal display device 10, roughly as shown in FIG. 1 , includes: a pair of glass substrates 11, 12 arranged to face each other with a predetermined gap therebetween; and a liquid crystal layer 13 sandwiched between the two glass substrates 11, 12. a sealant 14 for sealing the liquid crystal surrounding the peripheral portions of the two glass substrates 11, 12; The glass substrates 11 and 12 have a thickness of about 700 μm, the liquid crystal layer 13 has a thickness of about 3 to 5 μm, and the polarizing plate 15 has a thickness of about 300 μm.

[0041]On the surface of the liquid crystal layer 13 side of the glass substrate 11 on the upper ...

Embodiment approach 2

[0061] Embodiment 2 of the present invention will be described based on FIG. 10 . In the second embodiment, when the concave portion 21 is formed on the glass substrate 11, the terminal portion 23 of the glass substrate 12 is protected. Note that in this second embodiment, overlapping descriptions of the same configurations, actions, and effects as those of the first embodiment described above are omitted.

[0062] As shown in FIG. 10, the glass substrate 11 provided with the TFT 16 (switching element) in the liquid crystal display device 10 is formed to be larger than the glass substrate 12 provided with the filter layer and the counter electrode, so that the peripheral portion The terminal part 23 connected to each wiring 18 and 19 drawn out from TFT16 is provided in the state exposed to the outside. The terminal portions 23 are arranged in plural numbers (6 on the upper side in FIG. 10 and 3 on the left side in FIG. Terminal 23 provided at the upper end is connected to th...

Abstract

The invention provides a liquid crystal display and a method thereof. The liquid crystal display (10), comprising a pair of glass substrates (11) and (12) and a liquid crystal layer (13) installed therebetween. A recessed part (21) is formed in the surface of the glass substrate (11) on the opposite side of the liquid crystal layer (13) at a position corresponding to a foreign matter (X) (luminescent spot defective part). A light shielding layer (22) shielding a light is formed in the recessed part (21). Thus, a distance between the light shielding layer (22) and the foreign matter (X) can be reduced more than in a conventional case in which the light shielding layer is formed on the surface of the glass substrate and, accordingly, a light shielding range by the light shielding layer (22) can be further increased.

Description

technical field [0001] The present invention relates to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] An outline of a method of manufacturing a liquid crystal display device is described below. A switching element (such as a TFT) and a pixel electrode are provided on one glass substrate of a pair of glass substrates, and a counter electrode and the like are provided on the other glass substrate, and then the two glass substrates are separated by a small gap. stick together. Thus, liquid crystal is injected between the two glass substrates to form a liquid crystal layer, and then polarizing plates are attached to the surfaces of the two glass substrates, respectively. [0003] In the manufacturing process of the above-mentioned liquid crystal display device, various inspections are performed after each process to detect defective parts, but in the inspection performed after the formation of the liquid crystal layer, a pair...
