  • Patent number: 9134837
    Abstract: In a display apparatus, a first substrate includes a plurality of pixels and a plurality of first signal lines connected to the pixels. A second substrate includes a plurality of sensors and a plurality of second signal lines connected to the sensors and extended in a direction in which the first signal lines are extended. Each of the second signal lines is disposed between two first signal lines adjacent to each other and disposed closer to a center line, which divides an area between the two first signal lines into two portions, than the two first signal lines. Thus, signal interference between the first and second signal lines may be reduced, thereby preventing mis-operation or malfunction of the display apparatus.
