Abstract
The utility model provides a thin-film transistor TFT liquid crystal display panel and a set of display equipment. The TFT liquid crystal display panel comprises an array substrate and a color-film substrate. Liquid crystal is filled between the array substrate and the color-film substrate. Furthermore cylindrical spacing pads are provided between the array substrate and the color-film substrate. The cylindrical spacing pads are closely arranged to curve units with peaks or troughs. The curve units are staggered between a pixel area of the TFT array substrate and sealing glue. A channel for liquid crystal flow is formed at staggered area of adjacent curve units. The arrangement structure of the cylindrical pads of the TFT liquid crystal display panel enlarges the supporting force of the cylindrical pads to the TFT array substrate and the color-film substrate, and improves an obstruction function of the cylindrical pads to the flowing liquid crystal. Furthermore the channel is formed. The flowing liquid crystal is guided, thereby reducing or preventing a defect of sealing glue leakage which is caused by strong impact of liquid crystal flow to the sealing glue.
