LCD device having a smaller level difference |
摘要 |
The TFT substrate of an LCD device has an array of pixel electrodes defined by a plurality of signal lines and a plurality of scanning lines. Each terminal of the scanning lines includes a first metallic pattern, a second metallic pattern in contact with the first metallic pattern through a first via hole, and an ITO pattern in contact with the second metallic pattern through a second via hole. The ITO pattern has a width smaller than the width of the first via hole and larger than the second via hole, thereby providing the TFT substrate with a smaller level difference. The smaller level difference prevents the dust generated during a rubbing treatment from attaching onto the TFT substrate.
