Abstract

The invention discloses an electrode structure of a smectic LCD baseplate and a manufacturing method thereof. The electrode structure has the structure that an upper baseplate is provided with strip electrodes consisting of ITO electrodes and strip metal electrodes, wherein each strip electrode is provided with a vertically-conducted metal electrode; a lower baseplate is provided strip electrodes consisting of ITO electrodes and strip metal electrodes, wherein each vertically-conducted connection area is arranged at the clearance beside each strip electrode; and the vertically-conducted metal electrodes of the upper baseplate and the vertically-conducted connection areas of the lower baseplate are arranged correspondingly. The manufacturing method of the electrode structure comprises the following steps: cleaning the baseplates; forming the ITO electrodes; forming metal electrode base courses; and electroplating metal of the top layer to form metal electrodes. The electrode structure manufactured by the manufacturing method is compact, fully takes advantage of effective electrode areas, reduces ineffective electrode areas and can realize continuous splicing of a plurality of LCDs. The electrode structure is suitable for LCDs with larger pixel point areas and larger points among pixels, in particular for smectic LCDs.

Description

technical field [0001] The invention relates to an electrode structure and a manufacturing method thereof, in particular to an electrode structure of a smectic liquid crystal display substrate and a manufacturing method thereof. Background technique [0002] Currently, for a traditional liquid crystal display, there are mainly two driving methods for the electrodes on the display substrate: Active matrix and Passive matrix. [0003] For an electrode structure using an active driving method, a multi-layer thin film process is generally used to realize direct TFT (Thin Film Transistor, thin film transistor) driving of each pixel. At present, traditional liquid crystal displays and liquid crystal TVs with full-color large screens must adopt the electrode structure of this active driving method. However, this electrode structure is expensive, and the initial investment is too much. [0004] The electrode structure is very simple for an electrode structure using a passive drivin...

Problems solved by technology

However, this traditional electrode structure using a passive driving method is only suitable for small screens with low resolution and small pixel area, and since this electrode structure needs to leave enough space outside its effective electrode area to set The area where the upper and lower substrate electrodes are connected and the wiring, so the area of ​​the non-effective electrode area of ​​this electrode structure is very large, and multiple display screens cannot be spliced ​​very tightly, and the display effect after splicing is poor.
