Abstract: An organic EL display device includes scanning lines, video signal lines, and pixels, each including a TFT having a semiconductor layer and an organic EL layer located between a lower electrode and an upper electrode. A source electrode connecting the semiconductor layer and the lower electrode is formed of three layers including a barrier metal, an Al-containing metal, and a cap metal. The barrier metal is formed of a first layer in contact with the semiconductor layer and a second layer in contact with the Al-containing metal. Each of the first layer, the second layer, and the cap metal is formed of a metal comprising a high melting point metal, and an amount of oxygen in the first layer is larger than an amount of oxygen in the second layer.

Abstract: In a liquid crystal display device it is desirable to test in the state of TFT substrates, without reducing the number of TFT substrates to be obtained from one mother TFT substrate, and without increasing the overall size of the TFT substrates. Test terminals are formed on the outside of terminals for driving the liquid crystal display device. The test terminals of the specific TFT substrate are formed in another TFT substrate just below the specific TFT substrate. The area in which the test lines are formed is a space in which a sealing material is formed, between the display area and an end of the lower TFT substrate. Thus, the size of the TFT substrates is not actually increased. A test line area is not separately formed and not discarded, so that the number of TFT substrates to be obtained from one mother TFT substrate is not reduced.
