Patent ID: 7978275

Claim:
A display comprising a flexible substrate, TFTs arrayed on the substrate, and a plurality of pixels arrayed on the substrate and independently driven by the TFTs, wherein the flexible substrate has a difference in a thermal dimensional change ratio between two orthogonal directions consisting of a direction of a channel length between a source and drain of each TFT and a direction orthogonal to the direction of the channel length on the substrate, the thermal dimensional change ratio being an absolute value expressed by (L 80 -L 20 )/L 20 in which L 20 and L 80 are lengths of the substrate measured at 20° C. and 80° C. with respect to one of the two orthogonal directions of the substrate, respectively, and wherein the direction of the channel length between the source and drain of each TFT is along a direction, from among the two orthogonal directions on the substrate, in which the substrate has a smaller thermal dimensional change ratio than the other direction.
