Detailed description of the invention

Refer to Fig. 1~Fig. 3, it illustrates the display device according to an embodiment.Fig. 3 be along Fig. 1, The sectional view of A-A ' line in Fig. 2.Display device include first substrate 100, second substrate 200 and Multiple distance pieces 302.First substrate 100 includes that one first base material 102, component structure 104, is exhausted Edge layer 106, one pixel electrode layer 110 and one fills and leads up layer 112.Component structure 104 is formed at the first base On material 102.Insulating barrier 106 is formed on component structure 104.Insulating barrier 106 has at least one perforation 108.Pixel electrode layer 110 is formed on insulating barrier 106, and the pixel electrode layer 110 of a part extends Electrically connect to perforation 108 and with component structure 104.The corresponding perforation of pixel electrode layer 110 108 positions Form a concave part 1100.Fill and lead up layer 112 to be formed on pixel electrode layer 110, and fill up concave part 1100.Second substrate 200 is arranged at the offside of first substrate 100.Distance piece 302 is positioned at first substrate Between 100 and second substrate 200 and be correspondingly arranged in and fill and lead up on layer 112.

Specifically, the component structure 104 of first substrate 100 can include multi-strip scanning line 116, a plurality of 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 Can be formed by indium tin oxide (ITO), passivation layer 134 can be by silicon nitride (SiNx) formed.Insulating barrier 106 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 Plate 200 may also include overlying strata 208, is covered in chromatic filter layer 204 and black-matrix layer 206. Second substrate 200 may also include both alignment layers 210, is formed on overlying strata 208.

Display device may also include a liquid crystal layer 300, is arranged at first substrate 100 and second substrate 200 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.
