Patent ID: 7352003

Claim:
A camera comprising: an eyepiece; operation switches; and a display unit, the display unit comprising: an N-channel thin film transistor over a substrate, the N-channel thin film transistor including a gate electrode, a source region, a drain region, a channel region formed between the source and drain regions, a first LDD region formed between the channel region and the source region, and a second LDD region formed between the channel region and the drain region; and a P-channel thin film transistor over the substrate, the P-channel thin film transistor including a gate electrode, a source region, a drain region, and a channel region formed between the source and drain regions, wherein: a length of the gate electrode of the N-channel thin film transistor is shorter than a distance between the first LDD region and the second LDD region, at least one of the first LDD region and the second LDD region includes first and second sub-regions and an impurity concentration of the first sub-region is different from an impurity concentration of the second sub-region, and the N-channel thin film transistor and the P-channel thin film transistor constitute a CMOS circuit.
