摘要:
A liquid crystal display device having a liquid crystal display panel, where a liquid crystal layer is inserted as to be sandwiched between a pair of substrates, and which is provided with polarizers on opposite sides of the liquid crystal layer with the substrates residing between the polarizers, in which a light reflecting metal layer is formed on the inner surface of the substrate on a display surface, and an λ/4 retardation film is arranged between the substrate and the polarizer to serve as light reflection preventing means for the purpose of preventing the light reflected by the metal layer from outputting from the polarizer toward the display surface even if outside light is reflected by the metal layer. According to the present invention, an inexpensive liquid crystal display device is thereby obtained, where the diminution of contrast in the display due to the reflection of outside light by a black matrix is reduced.

A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

More specifically, it is preferable that the spacer member 40 consist of a soda glass substrate and that the liquid crystal display panel 36 for display be formed of non-alkali glass. With this constitution, it is possible to provide a stereoscopic image display device, which can be used as a large-sized stereoscopic image display device by means of the liquid crystal parallax barrier method, with good display quality and where due consideration has been given to the thermal expansion of the substrate caused by heat generated by the backlight, and the manufacturing method therefor.
