[0040] Figure 3A Shown is a schematic diagram of an active device array substrate according to a second embodiment of the invention. Figure 3B for Figure 3A A schematic cross-sectional view along the line C-C'. Please also refer to Figure 3A versus 3B The active device array substrate 300 of this embodiment is similar to the first embodiment, except that the electrical connection unit 320 of the active device array substrate 300 further includes a semiconductor layer 290 disposed on the first dielectric layer from which the second conductive pattern 250 has been removed. On the electrical layer 270, the semiconductor layer 290 is located between the first dielectric layer 270 and the second dielectric layer 280.

[0041] Since the semiconductor layer 290 is produced by a dry etching process, the underlying first dielectric layer 270 can be prevented from being over-etched, so the gradient of the film layer can be prevented from being discontinuous, and the technical effect of ...

Description

Technical field [0001] The present invention relates to an array substrate and a display panel, and more particularly to an active component array substrate with inspection units and a liquid crystal display panel with the active component array substrate. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation has gradually become the mainstream of displays. During display, the liquid crystal display panel selects a specific pixel through the scan line and the data line, and provides an appropriate operating voltage for the pixel to display the picture corresponding to the pixel. In particular, during the manufacturing process of the liquid crystal display panel, it needs to be tested to confirm that the manufactured liquid crystal display panel can operate normally. [0003] Generally speaking, a shorting bar design is u...
