摘要:
A thin film transistor (TFT) is formed on an insulating substrate, and a photosensitive resin film as an interlayer insulating film is formed so as to cover the TFT. Contact holes are formed in the photosensitive resin, and smooth concave and convex portions are provided on an upper surface of the resin. A film including molybdenum nitride (MoN) and a reflective pixel electrode film are successively laminated on the photosensitive resin. The nitrogen content in the MoN film may be between 5 atomic % and 30 atomic % inclusive.
摘要:
A difference of work functions in different metal thin films is suppressed without causing the increase of the manufacturing steps or the decrease of the optical performance. In a semi-transmissive reflective liquid crystal display apparatus 1 including a reflective electrode 62 and a transmissive electrode 63 in the pixel electrode 64, the surface of the reflective electrode 62 is subject to a plasma treatment, so that the work function of the reflective electrode 62 is controlled by changing by a value of 0.1 eV from the original value. Thus, it is possible to place the work function of the reflective electrode 62 within a difference of ±0.2 eV with respect to the work function of the transmissive electrode 63. As a result, a number of the manufacturing steps is not increased or no optical performance is decreased, unlike conventional liquid crystal display apparatuses. Even if the optimum direct current offset voltage is applied to one of the reflective electrode 62 and the transmissive electrode 63, it is possible to reduce the deterioration of an image display quality resulting from the difference with the optimum direct current offset voltage for the other electrode. As such, it is possible to improve the display quality of the liquid crystal display apparatus 1.

The substrate (10) of the present invention includes: a first electrode (26) and a second electrode (30). The second electrode (30) is formed on an insulation film (52) covering at least a part of the first electrode (26) and electrically connected with the first electrode (26) through a contact hole (50) formed in the insulation film (52). The first electrode (26) includes a laminated structure of a metal film (42) and a protective film (44). An etching rate of the metal film (42) is almost equal to an etching rate of the protective film (44) with respect to a first etching for forming the metal film (42) and the protective film (44). An etching rate of the protective film (44) is almost zero with respect to a second etching for forming the contact hole (50).

A distance (d1) from an edge of a first region (R) at places (D) where branch electrodes (4b) extending, which branch off from an electrode line (4a) of a second source/drain electrode (4), start to overlap with a first region (R) to the electrode line (4a) is 5 μm or more. This realizes a TFT including a comb-shaped source/drain structure that enables easy repair of a source-drain leakage.
