Abstract:
A stretchable interconnect includes a plurality of electrically conductive traces formed as a complex pattern on an elastic substrate. The form of the electrically conductive traces is such that when the elastic substrate is in a relaxed, or non-stretched, state each of the electrically conductive traces forms a tortuous path, such as a waveform, along the elastic substrate. The tortuous path of the electrically conductive traces provides slack such that as the elastic substrate is stretched the slack is taken up. Once released, the elastic substrate moves from the stretched position to the relaxed, non-stretched position, and slack is reintroduced into the electrically conductive traces in the form of the original tortuous path.

A signal line is provided in the dielectric element assembly and extends in the x-axis direction. A reference ground conductor is provided on a positive side in a z-axis direction relative to the signal line. An auxiliary ground conductor is provided on a negative side in the z-axis direction relative to the signal line. Via-hole conductors connect the reference ground conductor and the auxiliary ground conductor and are provided in the dielectric element assembly on the negative side relative to the center in a y-axis direction. A portion of the signal line in a section which includes the via-hole conductors is positioned on the positive side in the y-axis direction relative to another portion of the signal line in a section which does not include the via-hole conductors.

Provided is a configuration for a semiconductor layer and a line for reducing the segment length of the semiconductor layer with respect to the bending direction of the flexible substrate. Such a configuration reduces the probability of cracks occurring in the semiconductor layer of the thin-film transistor, thereby improving the stability and durability of the thin-film transistor employed in a curved or a flexible display device. The configuration includes a thin-film transistor (TF) on the flexible substrate. The TFT includes the semiconductor layer extending obliquely with respect to the direction of the line.
