Dark dot defect

The result of a transistor in the transparent electrode layer of an LCD being stuck 'on.'

A dark dot defect is a defective pixel that is typically caused by a transistor in the transparent electrode layer that is stuck "on" for TN panels or "off" for MVA, PVA, and IPS panels. In that state, the transistor places the liquid crystal material in such a way that no light ever passes through to the RGB layer of the display.
