Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to enforcement
In example or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, describe below
In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the display panels according to the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
With reference to Fig. 1, it is shown that according to the display panels 100 of the present invention, this display panels 100 includes
Substrate 101 and the organic layer 102 sequentially formed on this substrate 101 surface, gate metal layer 103, grid
Insulating barrier 104, source metal 105, drain metal layer the 106, first passivation layer 107, color blocking layer 108,
Second passivation layer 109 and pixel electrode layer 110, organic layer 102 is formed above running through color blocking layer 108 and
The via 111 of two passivation layers 109, pixel electrode layer 110 is formed with drain metal layer 103 by via 110
Electrical connection, thus the signal of telecommunication of drain metal layer 106 can pass to pixel electrode layer 110.Wherein, drain electrode gold
Belonging to layer 106 is source signal layer, it is possible to transmit the signal of telecommunication to pixel electrode layer 110, the first passivation layer 107
The steam being prevented from color blocking layer 108 with the second passivation layer 109 causes drain metal layer 106 and pixel electricity
Pole layer 110 aoxidizes, and it enables to metal surface and is converted into and is difficult to oxidized state, and delays metal
Corrosion rate.Pixel electrode layer 110 is made up of ITO (Indium Tin Oxides, tin indium oxide) material,
And the cross section of via 110 is inverted trapezoidal.
Wherein, the thickness of organic layer 102 is more than the thickness of drain metal layer 106, and is less than color blocking layer 108
Thickness, the drain metal layer 106 below via 110 is convex, it is possible to reduce drain metal layer 106
Distance with color blocking layer 108 upper surface, it is thus possible to ensure that via 110 degree of depth of display floater 100 is less than
Hole depth excessively of the prior art, such that it is able to the hole depth of crossing solving prior art crosses the pixel electricity taken an advanced study
The broken string of pole layer is bad, and on the premise of the inclination angle keeping hole wall is constant, it is possible to reduce via 110
Diameter, therefore, it is possible to improve the surface area of color blocking layer 108, and then improve aperture opening ratio, and again will not be because of
For organic layer 102 is blocked up, new problem occurs, such as section difference problem.
Additionally, during forming via 110, need the first passivation layer 107 is carried out photoetching and etching
Process thus form hole, therefore constant with the inclination angle crossing hole wall at the upper shed diameter keeping via 110
On the premise of, the under shed diameter of via 110 is more than the under shed diameter of via of the prior art, thus
The selectable scope of hole of the first passivation layer 107 is bigger, therefore, it is possible to avoid this hole and via 110
Para-position is forbidden the color blocking layer 108 caused to be etched, and causes the bubble in color blocking layer 108 to discharge, thus occurs
Liquid crystal bubbles.
As it is shown in figure 1, the cross section of gate metal layer 103 is trapezoidal, gate metal layer 103 is formed at substrate
On the surface of 101, it directly contacts with substrate 101.Gate metal layer 103 is coated with gate insulator 104,
This gate insulator 104 upwardly extends along the side on the surface being parallel to substrate 101, and covers organic layer
102.The effect of gate insulator 104 is isolation gate metal layer 103 and other metal levels, such as source electrode gold
Belong to layer 105 and drain metal layer 106.
The cross section of source metal 105 is also trapezoidal, and this source metal 105 is formed at gate metal layer 103
Top, drain metal layer 106 includes jut 161 and the par 162 being connected with this jut 161,
Jut 161 wraps above organic layer 102, and par 162 is along the surface being parallel to substrate 101
Side upwardly extend.Additionally, in FIG, color blocking layer 108 is divided into by organic layer 102 and via 110
Part I 181 and Part II 182, be provided with gate insulator between Part I 181 and substrate 101
104 and first passivation layer 107, and Part II 182 wraps above source metal 105.
Preferably, organic layer 102 is domed, and the outer surface of arch organic layer 102 is excessively natural, is conducive to
Drain metal layer 106 side of being coated on, certainly, organic layer 102 can also other shapes, the most trapezoidal,
Hemispherical etc..
Preferably, organic layer 102 is photoresist, and photoresist is the material that field of liquid crystals is the more commonly used, its
Can be changed by characteristic after illumination, and curing performance is good, certainly, organic layer 102 can also be it
His resin material.
It is to be appreciated that the display panels 100 that the present embodiment provides can not include the first passivation layer 107
With the second passivation layer 109, but preferably, the display panels 100 that the present embodiment provides also includes
The first passivation layer 107 between drain metal layer 106 and color blocking layer 108 and be positioned at color blocking layer 108
And the second passivation layer 109 between pixel electrode layer 110.
Certainly, the substrate 101 provided in the present embodiment can be glass substrate, it is also possible to for other materials
Transparency carrier, illustrates the most one by one.
Present invention also offers a kind of display device, including the display panels mentioned in technique scheme.
Above disclosed be only present pre-ferred embodiments, certainly can not with this limit the present invention it
Interest field, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment,
