Patent ID: 8068198

Claim:
A liquid crystal display apparatus comprising: a liquid crystal display panel having an array substrate having a plurality of scanning lines and data lines arranged in a matrix pattern and a chip-mounting area on which an IC chip for driving liquid crystal is provided and a color filter substrate having a color filter layer provided thereon; a light-detecting unit having an optical sensor integrated in the liquid crystal display panel for detecting external light; a detection circuit connected via sensor laid-around lines connected respectively to a plurality of lines of the light-detecting unit; an illuminating unit that illuminates the liquid crystal display panel; and a control unit that controls the brightness of the illuminating unit on the basis of an output from the detection circuit; wherein at least the plurality of data lines on the array substrate are distributed to the chip-mounting area and are formed with terminals for bump terminals to be connected to bump terminals of the IC chip at an end thereof, leader lines are further distributed from the plurality of the terminals to be connected to the bump terminals toward the chip-mounting area and are formed with inspection terminals at ends thereof, a plurality of sensor inspection lines each connected at one end thereof to each of the plurality of sensor laid-around lines and extended at the other end thereof to the chip-mounting area are formed, and the sensor inspection lines are each formed at the other end thereof with a sensor detection terminal.
