[0051] Please refer to Figure 1A and 1B , Figure 1A It shows the top structural view of the liquid crystal display motherboard of the first embodiment of the present invention, Figure 1B Shows Figure 1A The cross-sectional structure diagram of the cross-hatching line formed by A and A'. The liquid crystal display motherboard 100 includes a first substrate 102 , a second substrate 104 and a liquid crystal layer 103 . The second substrate 104 is disposed parallel to the first substrate 102 , and the second substrate 104 includes a non-panel area 104 a , a panel area 104 b , traces 106 a , 106 b , 110 a , 110 b and an ESD protection device 108 . Traces 106 a , 106 b and ESD protection device 108 are disposed on panel area 104 b , while traces 106 a and 106 b are electrically connected to ESD protection device 108 . Traces 110a and 110b are disposed on the non-panel region 104a and are electrically connected to traces 106a and 106b, respectively. Traces 110a and 110b are al...

[0059] Please refer to Figure 4A and 4B , Figure 4A A circuit diagram showing the ESD protection device of the second embodiment of the present invention, Figure 4B Shows Figure 4A The cross-sectional structure diagram of the cross-hatching line formed by A and A'. The difference between this embodiment and the first embodiment is that this embodiment makes the wiring 406a, 406b, 410a and 410b a double metal wiring structure, and the wiring 406a and 410a and the wiring 406a The boundaries with 410b are respectively connected by traces 402a and 402b of a single metal layer (Single Metal) structure. There is an insulating layer 404a between the double metal layers of the traces 406a and 410a, and a contact hole (Contact Hole) 404b is formed in the insulating layer 404a, so that the double metal layers of the traces 406a and 410a can be electrically connected through the contact hole 404b. Next, the situation that the electrostatic discharge current generated by the elec...

[0063] Please refer to Figure 5 , which shows another circuit diagram of the ESD protection device according to the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that this embodiment uses a lightning rod (Lightning Protector) 502 to electrically connect to the traces 506a and 506b respectively, and the circuit structure of the lightning rod 502 and the traces 506a and 506b is used as ESD protection device 508 . In this way, when the electrostatic discharge generates an electrostatic discharge current, the lightning rod 502 can discharge the electrostatic discharge current through the tip discharge mechanism, preventing the electrostatic discharge current from being introduced into the liquid crystal display panel to achieve the electrostatic discharge protection effect.

Abstract

A mother board of liquid crystal display is prepared as setting liquid crystal layer between the first base plate and the second base plate, setting the first and the second wirings on face plate region, setting the first static discharge protective unit on face plate region and electric-connecting it to the first and the second wirings, setting the third and the fourth wirings on nonfaceplate region and electric-connecting them separately to the first and the second wirings.

Description

technical field [0001] The invention relates to a liquid crystal display motherboard (Sheet), in particular to a liquid crystal display motherboard provided with an electrostatic discharge (Electrostatic Discharge, ESD) protection device on a wire. Background technique [0002] In today's era of rapid technological development, liquid crystal display panels have been widely used in electronic display products, such as televisions, computer screens, notebook computers, mobile phones or personal digital assistants. In particular, the multi-domain alignment liquid crystal display panel prepared by polymer-stabilized alignment (PSA) technology has fast response time, wide viewing angle, high aperture ratio, and high contrast. And simple process and other advantages, has been a technology that has been valued by the industry. [0003] In the PSA technology, in the process of preparing the display panel, a small amount of reactive monomer (reactive monomer) is first added to the ...
