Embodiment
Fig. 2 is the schematic top plan view of the active assembly array base plate of one embodiment of the invention.See also Fig. 2, active assembly array base plate 200 comprises a substrate 210, a picture element array 220 and a plurality of light-shielding pattern 230, and wherein substrate 210 can be glass substrate, and can have light transmission.
Each picture element unit 223 comprises that a transistor and electrically connects transistorized pixel electrode.These transistors for example are thin film transistor (TFT)s, and all have gate (gate), source electrode (source) and drain (drain).Pixel electrode can be transparency conducting layer, its material for example be indium tin oxide (Indium Tin Oxide, ITO) or indium-zinc oxide (Indium Zinc Oxide, IZO).
Hold above-mentionedly, these transistorized gates electrically connect these scan wirings 221 respectively, and source electrode electrically connects these data wirings 222 respectively, and drain electrically connects these pixel electrodes respectively.Therefore, these transistors can be opened or close to these scan wirings 221, gives pixel electrode to control these data wiring 222 output voltages.
Above-mentioned a plurality of light-shielding patterns 230 are positioned at colorized optical filtering section 210b, and be disposed at respectively in the interior spacer region 2100 of colorized optical filtering section 210b, and be electrically insulated with this picture element array 220, wherein respectively the quantity of the light-shielding pattern 230 of this spacer region interior 2100 is a plurality of, and having certain distance between adjacent two light-shielding patterns, this distance is preferably between 5 microns to 8 microns.In addition, light-shielding pattern 230 is to be positioned between the two adjacent control distributions (221,222), and can be less than the distance between the two adjacent control distributions (221,222) from the width of sectional view light-shielding pattern 230.
In addition, these light-shielding patterns 230 can be a metal material or a light-proof material, and for instance, light-proof material can be an organic photoresistance.Secondly, these light-shielding patterns 230 can avoid producing between the signal line situation of light leak, to reach good shaded effect.
The shape of light-shielding pattern 230 can be a strip.Therefore, in this spacer region respectively, the design of light-shielding pattern can be a plurality of discontinuous strips and arranges, and these discontinuous strips are arranged light-shielding patterns design, can avoid the accumulation of electric charge, reduce the probability that static discharge takes place.Secondly, these light-shielding patterns 230 can be designed to a dotted line (Dotted line) pattern, generally speaking, because of dashed pattern has less graphics area than solid pattern, so can prevent the accumulation of electric charge, but not undermine the function of its shading, and the design of dashed pattern, the transmission of electric charge capable of blocking does not again allow static to conducted inside, the generation of further anti-system electrostatic breakdown.
Fig. 3 is the local enlarged diagram of the active assembly array base plate among Fig. 2.Please refer to Fig. 3, in a plurality of light-shielding patterns 230 in this spacer region 2100 respectively, one of them light-shielding pattern 230 is one to have the light-shielding pattern 230a of ground connection design.
Fig. 4 be for the plurality of groups of substrates of thin-film transistor drawn along the I-I ' profile line of Fig. 2 in the diagrammatic cross-section of colorized optical filtering section.See also Fig. 2 and Fig. 4, in this embodiment, the scan wiring 221 in the 210b of colorized optical filtering section is to be made by the first metal layer (M1), and data distribution 222 is to be made by second metal level (M2).
Therefore, the light-shielding pattern 230 that is disposed at 221 of adjacent two scan wirings can be made by second metal level (M2), as the shading design of scan wiring 221.
In like manner, the light-shielding pattern that is disposed at adjacent two data wirings 222 then forms when making the first metal layer (M1), designs as the shading and the electrostatic prevention of data wiring 222.
That is to say that when carrying out the patterning process of the first metal layer (M1), it can form scan wiring 221 and the light-shielding pattern 230 that is disposed at adjacent two data wirings 222 simultaneously.When carrying out the patterning process of second metal level (M2), can form data wiring 222 and the light-shielding pattern 230 that is disposed at adjacent two scan wirings 221 simultaneously.By this, these light-shielding patterns 230 can be avoided 222 of data wirings or 221 situations that produce light leak of scan wiring respectively.
In this embodiment, light-shielding pattern 230 is except that can being made by metal material, and it also can be made by light-proof material, as: organic photoresistance.In addition, dispose an insulation course 240 (being so-called lock insulation course) on the first metal layer (M1), so that light-shielding pattern 230 is electrically insulated with scan wiring 221.
Moreover, on scan wiring 221 and data wiring 222, dispose a protective seam 250 equally, avoid being undermined in order to protection scan wiring 221 and data wiring 222 and make moist, and the assembly of scan wiring 221 and data wiring 222 and its top is electrically insulated.
Fig. 5 be for the plurality of groups of substrates of thin-film transistor drawn along the I-I ' profile line of Fig. 2 in another embodiment diagrammatic cross-section of colorized optical filtering section.See also Fig. 5 and Fig. 2, in this embodiment, the scan wiring 221 in the 210b of colorized optical filtering section is to be made by the first metal layer (M1), and data distribution 222 is to be made by second metal level (M2).
On the first metal layer (M1), dispose an insulation course 240 (being so-called lock insulation course).In addition, on scan wiring 221 and data wiring 222, dispose a protective seam 250 equally, avoid being undermined in order to protection scan wiring 221 and data wiring 222 and make moist, and the assembly of scan wiring 221 and data wiring 222 and its top is electrically insulated.
What need special instruction is that in this embodiment, 250 of protective seams are covered in light-shielding pattern 230.
The material of light-shielding pattern 230 can be that a light-proof material is formed in the present embodiment, and for example light-proof material can be a resin.So, when the material of light-shielding pattern 230 is a resin, the method for making of light-shielding pattern 230 can with practise black matrix (Black Matrix) identical.That is to say that when making of matrix (Black Matrix) deceived in general formation, black matrix (Black Matrix) can form simultaneously with light-shielding pattern 230.What must special one carry is, light-shielding pattern 230 designs at this moment are because of considering the demand of shading, so during from sectional view, the width of light-shielding pattern 230 is greater than the distance between this two adjacent control distribution (221,222).
Therefore, light-shielding pattern 230 also can be avoided the situation of static discharge injury in the known techniques except the shaded effect that can reach black matrix (Black Matrix).
In sum, in active assembly array base plate of the present invention, have a plurality of light-shielding patterns owing to be disposed between the control distribution in the septal area, and have certain distance between adjacent two light-shielding patterns.Therefore, in the manufacture process of LCD, or in the LCD running, when static discharge (Electrostatic Discharge takes place, ESD) or when having surging to produce, disconnect come the light-shielding pattern design, can reduce the static surging and enter to chance in the empty picture element region, improve antistatic capacity, further increase the yield of product.
Though the present invention discloses as above with previous embodiment, so it is not in order to limiting the present invention, anyly has the knack of alike skill person, and without departing from the spirit and scope of the present invention, institute does to change and the equivalence replacement of retouching, and still is in the scope of patent protection of the present invention.
