ACTIVE MATRIX DISPLAY DEVICE, AND INSPECTION METHOD THEREFOR

摘要

PURPOSE: To provide a liquid crystal cell and an inspection method therefor for efficiently inspecting picture quality of the liquid crystal cell before a driver IC is connected therewith. CONSTITUTION: The liquid crystal cell 11 has circuits 4, 5 for inspection. The circuits for inspection comprise each scanning signal wiring 11 or TFTs 22 for inspection connected with each signal wiring 12, inspection terminals 31-35 to be connected with the scanning signal wiring 11, and inspection terminals 41-45 to be connected with the signal wiring 12. Each inspection terminal is connected with multiple inspection TFTs 22. A display area is split into multiple blocks, and each block is connected with a set of scanning side inspection terminals and a set of signal side inspection terminals. Scanning signal wiring and signal wiring for a specific area are allocated to each block. Since multiple signal lines are properly put together with the TFTs and terminals for inspection, necessary image quality inspection can be carried out without using a multi-pin probe.
