Embodiment 1
[0095] In this embodiment, the level difference compensation pattern is formed by using the gate metal layer, and the gate electrode, the gate line and the level difference compensation pattern are simultaneously formed through one patterning process.
[0096] Figure 4 is a schematic plan view of the array substrate of this embodiment, Figure 5 for Figure 4 A-B cross-sectional schematic diagram of the array substrate shown, from Figure 4 and Figure 5 It can be seen in the figure that a level difference compensation pattern formed by the gate metal layer is provided under the edge of the data line, Figure 5 The number of film layers under the alignment layer 17 at positions 1, 2, 3, 4, and 5 is 4, 3, 4, 5, and 6 in sequence. It can be seen that it is because of the existence of the level difference compensation pattern that the level difference of the film layer no longer like figure 2 In that way, jumping directly from 4 to 6, a step structure is formed at the edge...
Embodiment 2
[0108] In this embodiment, the active layer is used to form the level difference compensation pattern, and the pattern of the active layer and the level difference compensation pattern are simultaneously formed through one patterning process.
[0109] Figure 7 is a schematic plan view of the array substrate of this embodiment, Figure 8 for Figure 7 A-B cross-sectional schematic diagram of the array substrate shown, from Figure 7 and Figure 8 It can be seen in the figure that a level difference compensation pattern formed by the active layer is provided under the edge of the data line, Figure 8 The number of film layers under the alignment layer 17 at positions 1, 2, 3, 4, and 5 is 4, 3, 4, 5, and 6 in sequence. It can be seen that it is because of the existence of the level difference compensation pattern that the level difference of the film layer no longer like figure 2 In that way, jumping directly from 4 to 6, a stepped structure is formed at the edge of the da...
