Description
Technical field
The present invention relates in particular to a kind of display panel and display device that prevents static discharge about a kind of display panel and display device.
Background technology
LCD is the high photovoltaic of conformability, and correlation technique contains thin film transistor (TFT) manufacturing process, liquid crystal material, panel assembling, drive IC design, structure packing technique and system, control circuit etc.With regard to demand material, liquid crystal material, indium tin oxide-coated glass (Indium Tin Oxide, ITO), colored filter (Color Filter, CF), backlight, polaroid and phase retardation film all be material indispensable in process for manufacturing liquid crystal display.
See also Fig. 1, Fig. 2 and Fig. 3, Figure 1 shows that the synoptic diagram of the display panels of prior art, Figure 2 shows that the schematic top plan view of the colored filter substrate of the display panel among Fig. 1, Figure 3 shows that display panel among Fig. 1 is along the diagrammatic cross-section of AA ' line.Panel of LCD 1 is main by first glass substrate 2 (colored filter substrate) that contains colored filter and after containing 3 pairs of groups of second glass substrate (thin film transistor base plate) of a plurality of thin film transistor (TFT)s, and the centre pours into liquid crystal material 9 and makes.Wherein colored filter substrate 2 is divided into viewing area 5 and neighboring area 6, and wherein viewing area 5 and neighboring area 6 separate by photo-shield strip 7, and photo-shield strip 7 is black matrix" for example.In addition, the frame glue 10 that also has bonding first substrate 2 and second substrate 3 in photo-shield strip 7 peripheries.Liquid crystal material 9 is sealed between first substrate 2, second substrate 3 and the frame glue 10.And also be provided with layer of transparent conductive layer 8 on the colored filter substrate 2, for example be that indium tin oxide-coated glass layer (Indium Tin Oxide, ITO)) is used for producing the voltage that liquid crystal 9 is turned to.But since in the viewing area 5 and neighboring area 6 all be coated with ITO layer 8, after 3 groups of colored filter substrate 2 and TFT substrates are upright, this framework but can add the stray capacitance that focuses on non-display area, because the ITO layer of neighboring area 6 can directly contact with air, thereby between drive integrated circult (IC) 4, form discharge circuit at air, make static discharge (Electrostatic Discharge, ESD) be easy to enter display panel 1 edge, thereby can cause occurring phenomenons such as display panel 1 demonstration is undesired, drive IC 4 damages, badly influence the quality of LCD.
Summary of the invention
In view of this, the objective of the invention is to by the viewing area at the colored filter substrate of display panel transparency conducting layer is set, then is not have conductive layer on its neighboring area or the cabling.This display panel structure can prevent that transparency conducting layer from directly contacting with air, realization from the air to the drive IC between the discharge off circuit, thereby effectively reduce the stray capacitance on the display panel peripheral circuit, improve the drives ability and avoid static discharge to disturb drive IC etc.
For reaching above-mentioned purpose, the invention provides a kind of display panel, this display panel comprises first substrate, to second substrate and liquid crystal layer that should first substrate.First substrate has viewing area, neighboring area, separation viewing area and neighboring area and is positioned at the photo-shield strip and the transparency conducting layer of viewing area periphery, and transparency conducting layer is arranged at this viewing area.Liquid crystal layer is sealed between this first substrate and this second substrate.
As optional technical scheme, this first substrate is a colored filter substrate.
As optional technical scheme, this second substrate is a membrane transistor pipe array base palte.
As optional technical scheme, this photo-shield strip is a photoresist.
As optional technical scheme, this display panel also comprises the frame glue that is positioned at peripheral also bonding this first substrate of this photo-shield strip and this second substrate.
As optional technical scheme, has electronic package on this second substrate.
As optional technical scheme, this electronic package is a drive integrated circult.
The present invention also provides a kind of display device, and this display device comprises: aforesaid display panel and the module backlight that light source is provided for this display panel.
Can be about the advantages and spirit of the present invention by following detailed Description Of The Invention and appended graphic being further understood.
