Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail, but not as a limitation of the invention.
Figure 1A is a kind of upper schematic diagram of dot structure according to one embodiment of the invention.Figure 1B is the pixel of Figure 1A The close-up schematic view of one embodiment of structure.Fig. 1 C and Fig. 1 D are shown along the section of hatching line I-I, II-II of Figure 1B respectively It is intended to.Figure 1A to Fig. 1 D is refer to, dot structure 100 includes substrate 110, insulating layer 120 and pixel electrode 130.Substrate 110 Can be glass substrate, silicon substrate, bendable plastic substrate or known any substrate that can be applied to make display panel.Base Plate 110 has surface S1.Insulating layer 120 and pixel electrode 130 are configured on the S1 of surface, and insulating layer 120 and pixel electricity Pole 130 is not limited to directly contact with surface S1.
Specifically, other film layers or component can have first been made on the S1 of surface, has just made insulating layer 120 and pixel electrode 130.For example, before making pixel electrode 130, scan line SL, data cable DL and active can be initially formed on the S1 of surface Element AD.Scan line SL and data cable DL are interlaced with each other, and are, for example, not to be in contact but vertically.Active member AD respectively with Scan line SL, data cable DL and pixel electrode 130 are electrically connected.
As shown in Figure 1A, active member AD have grid G E, channel layer CH, source S E and drain D E, wherein grid G E Scan line SL is connected to, source S E is connected to data cable DL and drain D E is connected to pixel electrode 130.Grid in active member AD Pole GE must separate without being in contact with channel layer CH, and scan line SL must also be separated without connecting with data cable DL Touch, and pixel electrode 130 can not be directly contacted with scan line SL, data cable DL and channel layer CH.Therefore, dot structure 100 In be provided with insulating layer 120 to realize the separation between these components.For the present embodiment, insulating layer 120 is not required to be defined to The structure of simple layer, and can be stacked to form by multiple insulation material layers.For example, insulating layer 120 may include not illustrate The first insulation material layer and the second insulation material layer, wherein the first insulation material layer be arranged at grid G E and channel layer CH it Between and scan line SL and data cable DL between, and the second insulation material layer is arranged between pixel electrode 130 and data cable DL And between pixel electrode 130 and channel layer CH, but not limited to this.In another embodiment, insulating layer 120 or simple layer Structure, and may be configured with other insulating layers in dot structure 100.In addition, insulating layer 120 is not required to limit with homogenous material group Into, wherein form insulating layer 120 insulating materials can be selected from by silica, silicon nitride, silicon oxynitride, insulation photoresist, Organic insulation or other one of which or combination in material of insulating effect can be provided.
Before pixel electrode 130 is made, insulating layer 120 can be patterned and define the first area A1 and be centered around The second area A2 in the first area A1 peripheries.In the present embodiment, the boundary B of the first area A1 and the second area A2 form a closed pattern. Figure 1B indicates the boundary B of the first area A1 and the second area A2 with thick dashed line, is the first area A1 wherein within thick dashed line, and thick dashed line It is the second area A2 in addition.The closed pattern is, for example, the square pattern shown in Figure 1B, that is, the first area A1 and the second area A2's Contoured profiles of the boundary B along square pattern.
There is height offset between first area A1 and the second area A2.Furthermore, the first area A1 has first area's top surface T1, and the second area A2 has the second area top surface T2.First area top surface T1 and the second area top surface T2 can be parallel to surface S1 Plane, and the first distance D1 of the first area top surface T1 to surface S1 be less than the second area top surface T2 to surface S1 second distance D2.For example, the difference of the first distance D1 and second distance D2 can between 0.3 micron to 0.9 micron, and preferably 0.5 Micron.
In the present embodiment, when insulating layer 120 is made of the insulation material layer of multiple layers of different materials, insulating layer 120 exists The material of first area top surface T1 can be identical or different from material of the insulating layer 120 in the second area top surface T2.In other words, absolutely Edge layer 120 is made of the insulation material layer of multiple layers of different materials, and the insulation material layer of top is local in the first area A1 It is thinned and forms the first area top surface T1, then insulating layer 120 is pushed up in the material of the first area top surface T1 with insulating layer 120 in the secondth area The material of face T2 can be identical.In addition, insulating layer 120 is made of the insulation material layer of multiple layers of different materials, and top Insulation material layer be removed completely in the first area A1 and the surface of time top layer is formed the first area top surface T1, then insulating layer 120 the first area top surface T1 material and insulating layer 120 be in the material of the second area top surface T2 possible be different.
Pixel electrode 130 is formed at after insulating layer 120, and pixel electrode 130 and drain D E is electrically connected to each other.Such as figure Shown in 1C and Fig. 1 D, at least part area of pixel electrode 130 continuously extends to the second area top surface T2 by the first area top surface T1.
