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.

摘要： The present invention provides a semi-transmissive liquid crystal display device that can suppress flicker by adjusting an optimum value of a direct-current offset voltage that is applied to offset a bias electric field generated inside liquid crystal without increasing the number of production steps, and also provides a preferable production method of the semi-transmissive liquid crystal display device. The liquid crystal display device of the present invention is a semi-transmissive liquid crystal display device including: a substrate on aback face side, including a transmissive electrode and a reflective electrode; a substrate on an observation face side, facing the substrate on the back face side; and a liquid crystal layer arranged between the substrate on the back face side and the substrate on the observation face side, wherein the reflective electrode has a molybdenum-containing surface on a side of the liquid crystal layer.
