A composition that can be used as mold release agent is disclosed. An accumulated value associated with error counts is acquired when the recorded error count is greater than an error threshold value. Accordingly, waiting time is reduced in converting an input signal. The readout device and the sensing pad are disposed in a non-display region. The vendor computer transmits retrieved information to the device, and sales associate communicates timely and accurate product information to the consumer. The circuit is provided between the first insulating layer and the second insulating layer, includes an interconnect supplied with a drive current, and is configured to supply the drive current to the pixel electrode.
