  • Patent number: 9904130
    Abstract: There are provided connecting wires whose reliability may be ensured by preventing leakage between the connecting wires and by preventing entry of moisture. Overexposure is performed by using a mask having a shape of a protruding pattern (55a) with a sharp tip end at a position corresponding to a pattern edge of an organic insulating film (70) between adjacent connecting wires (50). Inclination of an inclined surface of the organic insulating film (70) sandwiched by the connecting wires (50) is thereby made gradual, and thus, at the time of forming the connecting wires (50), a film thickness of a resist may be prevented from becoming thick along an edge line of the organic insulating film (70). As a result, the resist is prevented from remaining in a connected manner at a region sandwiched by the adjacent connecting wires (50), and leakage between the adjacent connecting wires (50) may be prevented.

  • Patent number: 9869913
    Abstract: Inside of a region for inspection set outside a display region of an active matrix substrate, lead-out lines (27a to 27f) connected to data lines pass through in a column direction, and a control line for inspection (31) and six signal lines for inspection (32a to 32f) extend in a row direction. TFTs for inspection (51a to 51f) control a conduction state between the lead-out line and the corresponding signal line for inspection in accordance with a signal on the control line for inspection. Inside the region for inspection, three of the six signal lines for inspection are arranged on one side of the control line for inspection, and the remaining three are arranged on other side of the control line for inspection. One of the two adjacent lead-out lines is connected to one of the former signal lines for inspection via the TFT for inspection (51a, 51c, 51e), and the other is connected to one of the latter signal lines for inspection via the TFT for inspection (51b, 51d, 51f).
