Abstract
Disclosed are a flexible touch panel, a structure of which is changed to prevent cracks in touch wirings, and an organic light emitting display device using the same. The flexible touch panel includes transparent capping electrodes including at least three intersection points between first wirings and second wirings in each of adjacent first blocks and thus overlapping bridge electrodes.
