Data wire 118 and multiple thin film transistor (TFT) 120.Distance piece 302 arranges along scan line 116.First base
The component structure 104 of plate 100 may also include first interlayer insulating film the 122, second interlayer insulating film 124,
Guide hole 126 and cushion 128 etc..First interlayer insulating film 122 and the second interlayer insulating film 124 can
Respectively by silicon nitride (SiNx) and Si oxide (SiOx) formed.Pixel electrode layer 110 can be in perforation 108
Bottom is coupled to through the first interlayer insulating film 122 and guide hole 126 of the second interlayer insulating film 124, and
Scan line 116, data wire 118 and thin film transistor (TFT) 120 can be coupled further by guide hole 126.
Thin film transistor (TFT) 120 is as a example by low temperature polycrystalline silicon (LTPS) at the present embodiment, and actual application also can be answered
For other active layer materials such as oxide semiconductor layers.Pixel electrode layer 110 can include bottom electrode
130, top electrodes 132 and completely cut off the two passivation layer 134.Bottom electrode 130 and top electrodes 132

And fill and lead up layer 112 and can be formed by light sensitive material, such as acryl or silica-base material etc..By using
Light sensitive material, first can generally form in structure and fill and lead up layer 112, then remove unwanted part.?
In one embodiment, insulating barrier 106 and fill and lead up layer 112 and formed by identical material.Fill and lead up the upper of layer 112
The position on surface is higher than the upper surface of pixel electrode layer 110.In one embodiment, fill and lead up layer 112 to cover
Thickness on pixel electrode layer 110 is 0.5um～2um.First substrate 100 may also include a both alignment layers
114, it is formed at pixel electrode layer 110 and fills and leads up on layer 112, its spacers 302 is arranged at orientation
On layer 114.Both alignment layers 114 can be formed by polyimides (PI).
Second substrate 200 can include one second base material 202, chromatic filter layer 204 and a black matrix"
Layer 206.Black-matrix layer is formed on the second base material 202, is subsequently formed chromatic filter layer 204.Color
Color filtering optical layer 204 such as includes blue region 204B, red area 204R and green area 204G.
Black-matrix layer 206 defines the penetrating region T and non-penetrating district N of display device, is not wherein hacked colour moment
The scope i.e. penetrating region T that battle array layer 206 covers, the scope covered by black-matrix layer 206 is then non-penetrating
District N.Perforation 108 and distance piece 302 are arranged in the range of black-matrix layer 206 covers.Second base

Between.Distance piece 302 is positioned in liquid crystal layer 300.Distance piece can be photoresist formula distance piece.
In the display device according to the invention, fill and lead up layer by addition, the region that surface is smooth can be increased.
Consequently, it is possible to as shown in Figure 4, even if the position of distance piece is slightly offset from the top to perforation, also will not
There is the change on height by because perforation is affected, can avoid between two substrates separated by distance piece
Distance have the situation of variation, thus improve the concordance of substrate pitch.Resolution along with display device
Improving, elemental area and spacing all taper into, if not filling and leading up the setting of layer, the most very likely send out
Raw distance piece falls into the situation of perforation because of bit errors, and in turn resulting in the distance between two substrates has local
Change.Distance between two substrates has the biggest impact for penetration and the colourity of light, if sending out
Raw distance piece falls into the situation of perforation, and the optical characteristics that will cause display device is the best.Therefore, add
The design filling and leading up layer can improve the optical characteristics of display device, such as contrast (contrast ratio) etc..
Furthermore, owing to filling and leading up floor height in the certain height of pixel electrode layer, maintaining identical substrate interval
In the case of, can reduce to globality the size of distance piece.Consequently, it is possible to need to be hidden by black-matrix layer
The scope covered can reduce, and then improves the aperture opening ratio (aperture ratio) of display device.
Here, for convenience's sake, illustrate as a example by liquid crystal indicator.But, the present invention is also
Being not only restricted to this, any to have the display device that distance piece is arranged between two opposing substrate the most applicable.
Referring now to Fig. 5 and Fig. 6, it illustrates the display device according to different embodiments.Such two figures
Shown in, distance piece 302 can be located between two perforation 108.In one embodiment, as it is shown in figure 5,
Filling and leading up layer 112 can be band pattern.In another embodiment, as shown in Figure 6, filling and leading up layer 112 can be
Island-shaped pattern.
In sum, although combine preferred embodiment above and disclose the present invention, however itself and be not used to limit
Determine the present invention.Persond having ordinary knowledge in the technical field of the present invention, in the spirit without departing from the present invention
With in scope, can be used for a variety of modifications and variations.Therefore, protection scope of the present invention should be to enclose
What claim was defined is as the criterion.
