Abstract
An electrowetting display device includes a first support plate and an opposing second support plate and an electrowetting pixel region between the first support plate and the second support plate. A thin film transistor (TFT) structure is over the first support plate and associated with the electrowetting pixel region. The TFT structure includes a first metal layer over the first support plate. The first metal layer includes a gate and a reflective metal portion. A semiconductor layer is over the gate. A dielectric layer is on the first metal layer. The dielectric layer includes a first contact hole extending along at least a portion of a length of the dielectric layer. A light sensing element is disposed over the dielectric layer and in ohmic contact with the reflective metal portion.
