    Abstract: The present disclosure proposes a method of producing an LTPS TFT array substrate. The method is about stacking of a gate insulating layer and an interlayer insulating layer for providing conditions for formation of a gate trench. In addition, stacking of the gate insulating layer and the interlayer insulating layer is produced with some blocks of forming a hole on the gate insulating layer and the interlayer insulating layer to form a hole pattern, filling the gate trench, and producing gate lines. In this way, the formation of the gate lines and the formation of the hole pattern on the gate insulating layer and the interlayer insulating layer are done using the same mask. The method of the present disclosure reduces the number of masks required compared with the method of the related art, thereby reducing the production costs.

    Abstract: The present invention provides a TFT substrate manufacturing method and a TFT substrate. In the TFT substrate manufacturing method of the present invention, a pattern of the gate metal layer has been designed such that reflective blocks are included in a gate metal layer at locations corresponding to areas in which connection holes are to be formed so that in a process of forming the connection holes, light is reflected by the reflective blocks to enhance intensity of exposure on locations where the connection holes are formed. Thus, even under the condition that limit exposure size of an existing exposure machine is constrained, it is still possible to ensure full exposure in forming the connection holes in a high PPI display panel device to thereby realize production of high display panel products.
