A plurality of liquid crystal display cells in a test unit are driven to display a series of test image patterns. When some of the liquid crystal display cells are judged to function poorly or completely good, they are controlled to display a predetermined image pattern, so that an inspection person can stop further testing them and focus testing on other liquid crystal display cells. Where some of the other liquid crystal display cells are then judged to function poorly or completely good, they are controlled to display the same pattern as such a predetermined image pattern. Thus, since the inspector can test such liquid crystal display cells as required to check, the testing efficiency is significantly improved.
