Abstract

The utility model provides an array substrate and a display unit. The array substrate comprises a substrate and gate electrode wires. An anti-sliding structure is disposed on the surface of an uppermost film layer arranged in a boss area of the gate electrode wires. The array substrate can prevent a sub-PS from sliding when the sub-PS abuts against the gate electrode wires of the array substrate, reduce damages to a polyimide (PI) film at the gate electrode wires, thereby avoiding occurrences of white spot mura and improving qualified product rate.

In the such scheme, said aperture is circular hole or square hole.

In the such scheme, the diameter of said circular hole or the length of side of square hole are 2um.

In the such scheme, said anti-skid structure is one or more protruding pattern of forming.

In the such scheme, said convexity is circular protrusions or strip projected parts or netted convexity or annular projection.

In the such scheme, the height of said convexity is 2～4um.

In the such scheme, the rete of said the top is gate insulation layer or passivation layer.

A kind of display device that the utility model provides comprises like each described array base palte of claim 1 to 8.

Array base palte that the utility model provides and display device, the land area of the gate electrode line of array base palte is provided with anti-skid structure; So, can prevent to slide when Sub-PS from pushing up the gate electrode line of array base palte, reduce the damage of the gate electrode line PI of place film, and then avoid the bad generation of white point, improve yields.

Embodiment

The basic thought of the utility model is: the land area at the gate electrode line is provided with anti-skid structure.

Said land area is the zone that width increases or area increases on the gate electrode line.

Through accompanying drawing and specific embodiment the utility model is done further detailed description below.

The utility model provides a kind of array base palte, comprising: substrate, gate electrode line wherein, are provided with anti-skid structure on the surface of the rete of the top of the land area that is positioned at said gate electrode line.The rete of said the top is meant the outermost rete of rete of the gate electrode line top that is arranged in array base palte not comprise the oriented layer that is coated with in the box technology.The rete of said the top can be gate insulation layer, perhaps passivation layer, perhaps rete such as transparent electrode layer.

The anti-skid structure of the utility model embodiment; Aperture for the surface of the rete of the top of the land area 2 that is positioned at said gate electrode line; Zone as shown in Figure 2 is the land area 2 of part gate electrode line, the surface of the rete of the top of the land area 2 of said aperture setting and this gate electrode line.Said aperture can be Any shape, like shapes such as circular hole, square hole, trapezoidal hole or diamond holes.From to preparation technology's precision and convenient consideration, the shape of said aperture is preferably circular hole or square hole, and when said aperture was circular hole 5, the diameter of this circular hole 5 was generally 2um, when said aperture be square hole, the length of side of said square hole is generally 2um; As shown in Figure 3, present embodiment only shows the situation that said aperture is a circular hole 5.

Perhaps, said anti-skid structure is the convexity on surface of rete of the top that is positioned at the land area 2 of said gate electrode line, and said convexity can be circular protrusions or strip projected parts or netted convexity or annular projection or other convex in form; From the consideration to preparation technology and preparation precision, the height of said convexity is generally 2～4um.

Fig. 4 is the synoptic diagram when said convexity is circular protrusions 6; The synoptic diagram of Fig. 5 when being vertical bar shape convexity 7 when said convexity; The synoptic diagram of Fig. 6 when being horizontal stripe shape convexity 8 when said convexity; Fig. 7 is for being netted protruding synoptic diagram 9 time when said convexity, and Fig. 8 is the synoptic diagram when said convexity is annular projection 10.

Based on above-mentioned array base palte, the utility model embodiment also provides a kind of display device, and this display device comprises above-mentioned array base palte.

Said display device can have the device of Presentation Function for mobile phone, notebook computer, panel computer, liquid crystal panel, oled panel, Electronic Paper, LCD, monitor etc.

Through the technic relization scheme of the utility model, when the Sub-PS on the color membrane substrates was pushed, anti-skid structure can play the effect that stops Sub-PS, increases friction, and like this, Sub-PS just can not slide, and can the PI film not scratched; It is bad also just can not white point to take place, and has improved yields greatly.

The above; Be merely the preferred embodiment of the utility model; Be not the protection domain that is used to limit the utility model, obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and the scope of the utility model the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
