Problems solved by technology

For example, when the peripheral wiring connected to both ends of the barrier electrode is disconnected, or when two or more parts of the display area are disconnected, it will be visually recognized as a disconnection defect.
In addition, when the terminal part is destroyed by static electricity, a disconnection defect may also occur.
In Patent Document 1, there is also a problem that the yield rate at the time of manufacture is lowered due to insufficient countermeasures against disconnection due to static electricity.

Embodiment approach 1

[0075] Figure 5 It is a plan view showing an example of the structure of the first transparent substrate 21 according to the first embodiment of the present invention.

[0076] Such as Figure 5 As shown, the connection wiring 63 is formed to extend from each drive IC output terminal 57 to the outside of the first transparent substrate 21. The short-circuit ring 64 is formed outside the first transparent substrate 21. In the first embodiment, the feature is that each drive IC output terminal 57 is connected to the short-circuit ring 64 via the connection wiring 63. Since the other structure is the same as the premise technology, detailed description is omitted here.

[0077] Figure 5 The manufacturing process of the display device 1 is shown, specifically, the manufacturing process of the parallax barrier louver panel 20 is shown. In the manufacturing process of the parallax barrier louver panel 20, the first transparent substrate 21 is for example Image 6 The TFT array substr...

Embodiment approach 2

[0085] Picture 10 It is a plan view showing an example of the structure of the first transparent substrate 21 according to the second embodiment of the present invention.

[0086] Such as Picture 10 As shown, the short-circuit ring 64 is formed in the first transparent substrate 21. The second embodiment is characterized in that a high resistance element 65 is provided between each drive IC output terminal 57 and the short-circuit ring 64. That is, each drive IC output terminal 57 is connected to the short-circuit ring 64 via the connection wiring 63 and the high resistance element 65. Since the other structure is the same as the premise technology, detailed description is omitted here.

[0087] The high-resistance element 65 can be formed of, for example, a fine pattern of a high-resistance material such as amorphous silicon or ITO.

[0088] Based on the above description, according to the second embodiment, a high-resistance element 65 is provided between each drive IC output t...

Embodiment approach 3

[0092] Picture 11 It is a plan view showing an example of the structure of the first transparent substrate 21 according to Embodiment 3 of the present invention.

[0093] Such as Picture 11 As shown, the short-circuit ring 64 is formed in the first transparent substrate 21. The third embodiment is characterized in that a spark gap 66 is provided between each drive IC output terminal 57 and the short-circuit ring 64. That is, each drive IC output terminal 57 is connected to the short-circuit ring 64 via the connection wiring 63 and the spark gap 66. Since the other structure is the same as the premise technology, detailed description is omitted here.

[0094] Such as Picture 12 As shown, the spark gap 66 is a gap provided between the connecting wire 63 and the short-circuit ring 64.

[0095] Based on the above description, according to the third embodiment, a spark gap 66 is provided between each drive IC output terminal 57 and the short-circuit ring 64. Therefore, even if stati...

Abstract

According to the present invention, a display device includes a display panel, and a parallax barrier shutter panel. The parallax barrier shutter panel is provided to be opposed to the display panel.The parallax barrier shutter panel includes a plurality of first transparent electrodes, a drive IC, and an FPC. The plurality of first transparent electrodes are provided at regular intervals. The drive IC is configured to control a voltage to be applied to each of the plurality of first transparent electrodes. The FPC includes an FPC terminal electrically connected to an input terminal of the drive IC. At least one of each of the plurality of first transparent electrodes, an output terminal of the drive IC, and the FPC terminal is electrically connected to a short ring.

Description

Technical field [0001] The present invention relates to a display device provided with a parallax barrier louver panel and a manufacturing method thereof. Background technique [0002] Conventionally, as a naked-eye stereoscopic image display method capable of stereoscopically observing an image without special glasses, a parallax barrier method is known. The display device of the parallax barrier method includes: a parallax barrier panel, which is also called a transmissive display device; a barrier generating unit that generates a plurality of striped barriers through electronic control; and a display screen, which is arranged behind the parallax barrier panel By displaying a multi-directional image in which left-eye images and right-eye images are alternately arranged corresponding to the parallax barrier, stereoscopic viewing can be realized. [0003] In such a display device, since the barrier can be electronically generated, and the shape, position, and density of the genera...
