摘要： A method of manufacturing a liquid crystal display device is intended to decrease the number of manufacturing steps. The liquid crystal display device is arranged so that in each pixel area provided on a liquid-crystal-side surface of one of a pair of substrates disposed to oppose each other with a liquid crystal interposed therebetween, a signal from a drain line is applied to a pixel electrode via a drain electrode and a source electrode which are formed in a layer overlying a semiconductor layer of a thin film transistor, by the supply of a scanning signal from a gate electrode which is positioned as an underlying layer with respect to the semiconductor layer. The method of manufacturing such liquid crystal display device includes the steps of: forming a stacked structure in which the semiconductor layer and a first conductive layer are sequentially stacked in the same pattern, in both an area for forming the drain signal and an area for forming the thin film transistor; and after forming a second conductive layer, by using the same mask, providing separation between the drain electrode and the source electrode of the thin film transistor and also forming the pixel electrode connected to the source electrode.

摘要： 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.

摘要： A liquid crystal display device, or more particularly, an active matrix type liquid crystal display device having a pixel electrode formed in a pixel field defined on one of two transparent substrates opposed to each other with a liquid crystal layer between them. The pixel electrode is overlapped a signal line, which is formed in a portion of the one transparent substrate coincident with a black matrix, with a dielectric between them. The width of the overlap is set to a value satisfying a condition that an electric field induced between the signal line and pixel electrode will not invade into the pixel field defined with the black matrix. Owing to the structure, inhomogeneous luminance caused by a source electrode of a thin film transistor can be avoided. Moreover, inhomogeneous luminance caused by a capacitive element can be avoided.

摘要： To prevent the peeling-off of a drive circuit chip from an insulation substrate of a display device attributed to a residual stress between terminals formed on the insulation substrate and bumps formed on a mounting surface of a drive circuit chip, as well as to stabilize the connection resistance therebetween, the present invention provides an auxiliary bump for one of the bumps on the mounting surface of the drive circuit chip at an end edge side thereof with respect to the one of the bumps and arranges the auxiliary bump electrically in contact with one of the terminals formed on the insulation substrate of the display device with which the one of the bumps also is in electrical contact. Since the one of the bumps is spaced from the end edge side of the mounting surface of the drive circuit chip by the auxiliary bump, electrical contact thereof with the one of the terminals cannot be affected by the atmosphere, in which the display device is used, and distortion of a signal waveform caused thereat can be suppressed also.
