Fig. 2 is the structural representation of signal wire in the line segment part close to input signal end of display panel of the present invention.

[embodiment]

For allowing above-mentioned purpose of the present invention, feature and advantage become apparent, present pre-ferred embodiments cited below particularly, and coordinate accompanying drawing, be described in detail below.Moreover, the direction term that the present invention mentions, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " side " etc., be only the direction with reference to annexed drawings.Therefore, the direction term of use is in order to illustrate and to understand the present invention, and is not used to limit the present invention.

Shown in seeing figures.1.and.2, present invention is disclosed a kind of display panel, described display panel can be a liquid crystal display panel of thin film transistor, the liquid crystal layer substantially comprising two substrates be oppositely arranged and be arranged between substrate.As shown in Figure 1, wherein on a substrate, its surface can be provided with many signal line 10, and described signal wire 10 can comprise multi-strip scanning line 10a and a plurality of data lines 10b, and wherein said sweep trace 10a extends in the horizontal direction, and interval side by side to each other; Described data line 10b then vertically extends, be spaced side by side and with described sweep trace 10a vertical interlaced, thus define multiple in matrix arrangement pixel cell 102.In each pixel cell 102, be generally provided with a thin film transistor (TFT), it connects wherein a sweep trace 10a and wherein a data line 10b and a pixel electrode simultaneously.Described thin film transistor (TFT) can accept the sweep signal of sweep trace 10a and open, and makes the data-signal of data line 10b be transferred to described pixel electrode by described thin film transistor (TFT) immediately.

As shown in Figure 1, described display panel mainly comprises viewing area 1 and a non-display area 2, and described pixel cell A is distributed in described viewing area 1.Described non-display area 2 is around described viewing area 1, and described non-display area 2 comprises the fan-out area of described display panel.At least one input signal end 200 is provided with, in order to connect scan driving circuit or a data drive circuit in described non-display area 2.

As shown in Figure 1, the signal wire 10 of described display panel is connected between pixel cell 102 in described viewing area 1 and the input signal end 200 of described non-display area 2.Shown in Fig. 2, described signal wire 10 has the live width such as not, and wherein minimum feature is at least greater than 5 microns.For example, described signal wire 10 such as can have larger live width in the line segment part close to described input signal end 200.

In the present embodiment, as shown in Figure 2, described signal wire 10 is trapezoidal in the line segment part 100 close to described input signal end 200, described trapezoidally have one away from the first base 100a and of described input signal end 200 near the second base 100b of described input signal end, and described first base 100a length is less than described second base 100b.That is, the live width of described signal wire 10 is more larger close to described input signal end 200.Through experimental verification, when test probe 3 as shown in Figure 2 contacts connection pad on described input signal end 200 to give test signal, the line segment part 100 that described signal wire 10 has larger live width can provide a buffering effect for sparking of electrostatic, immediate current is reduced, reduces the impact that static discharge causes.
