Problems solved by technology

[0010] However, ITO patterns, which are generally used as sensing patterns of touch screen panels, may have poor flexibility and may be easily broken or damaged when contraction force, expansion force, or bending force is applied thereto.
Therefore, the desired flexibility performance may not be achieved

Embodiment 1

[0109] A sensing pattern with a thickness of 45 nm was formed on a COP (chip on plastic) substrate with a thickness of 40 μm. In the sensing pattern, a first pattern is formed along a first direction to include unit patterns connected by connection parts; and a second pattern is formed along a second direction (perpendicular to the first direction) to include unit patterns isolated from the connection parts. unit pattern.

[0110] An insulating layer is formed on the connecting portion (line width: 130 μm) of the first pattern, and an ITO bridge electrode (line width: 30 μm, thickness: 135 nm) is formed on the insulating layer along the second direction so that the isolation unit pattern of the second pattern is electrically connected. connected to obtain a touch sensor laminate.

[0111] The angle between the stretching direction of the polarizing plate and the length direction of the connecting portion is 0°. The angle between the stretching direction of the polarizing pla...

Embodiment 2

[0113] The same process as described in Example 1 was carried out to obtain a touch sensor laminate, except that the angle between the stretching direction and the lengthwise direction of the connection part was 15°, and the stretching direction was 15° from the lengthwise direction of the bridge electrodes. The angle between them is 75°.

Embodiment 3

[0115] The same process as described in Example 1 was carried out to obtain a touch sensor laminate, except that the angle between the stretching direction and the length direction of the connection part was 30°, and the stretching direction was 30° to the length direction of the bridge electrodes. The angle between them is 60°.

Abstract

A touch sensor laminate includes a polarizing plate having a predetermined stretching direction, and a sensing pattern layer formed on at least one surface of the polarizing plate. The sensing patternlayer includes a first pattern formed along a first direction, a second pattern formed along a second direction, and a bridge electrode electrically connecting isolated unit patterns included in thesecond pattern. The first pattern includes a plurality of unit patterns, and a connection portion connecting neighboring unit patterns of the plurality of unit patterns, the connection portion havinga width smaller than a maximum width of the unit pattern of the first pattern. An angle between the stretching direction of the polarizing plate and a length direction of the connection portion is 60-degree or less.

Description

[0001] Cross References and Priority Claims to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0100006 filed with the Korean Intellectual Property Office (KIPO) on Aug. 5, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a touch sensor laminate, a touch screen panel, and an image display device including the same. Background technique [0004] The touch screen panel is an input device configured to transmit a user's instruction by selecting an object shown on, for example, a display plane of an image display device using a human hand or an additional input tool. [0005] For example, a touch screen panel may be disposed on the front of the image display device, and may convert a touch area in contact with a human hand or an input tool into an electric signal. An instruction to select in the touch area may be received as an input signal....
