Abstract: Provided are a display device capable of preventing burning by suppressing occurrence of a VCOM shift which occurs when a liquid crystal panel is driven for a long period of time, and a drive method thereof. Since a source output voltage corresponding to each of tone levels from a tone value 0 to a tone value 224 agrees with a flicker regulation voltage, a shift amount from the flicker regulation voltage is set to 0 mV, and a source output voltage corresponding to a tone value 255 is obtained by further adding +40 mV as a shift amount to 4.05 V which is the flicker regulation voltage. In such a manner, a source output voltage, increased at a high tone level and in the vicinity thereof, is applied to source bus lines SL1 to SLm and written into each liquid crystal capacitance Ccl.

Abstract: A backlight unit comprises a light source, a light guide plate and a frame. The light guide plate comprises a light guide and a low-refractive-index layer. The refractive index of the low-refractive-index layer is less than the refractive index of the light guide. A plurality of prisms for gradually reducing the angle of incidence of light coming from the light source with respect to the rear surface of the light guide are provided to the front surface or rear surface of the light guide. A plurality of prisms for totally reflecting forward the light coming from the light source are provided to the rear surface of the light guide plate. The frame comprises walls for surrounding the light source and the light guide plate. The width of the upper side of the walls and the width of the lower side thereof are substantially equal.

Abstract: A liquid crystal display device (100) includes a glass substrate (110) having an LSI chip (130) and an FPC board (140) mounted thereon. A component ACF (150a) made of a single sheet is used to further mount discrete electronic components such as stabilizing capacitors (150) on the glass substrate (110). The component ACF (150a) has a size that covers not only a region where the discrete electronic components are to be mounted, but also the top surfaces of the LSI chip (130) and the FPC board (140) which are mounted first. By thus using the large component ACF (150a), a positional constraint upon adhering the component ACF (150a) to the glass substrate (110) is eliminated, reducing the area of a region where the discrete electronic components are mounted. By this, a board module miniaturized by reducing the area of a region where discrete electronic components are mounted is provided.

A panel protective plate for protecting the display surface (11a) of the liquid crystal display panel (11) is formed integrally with the case (13).

Abstract: The present invention provides a display panel in which, without providing connection terminals, the number of which corresponds to the number of test terminals of a liquid crystal panel, on a circuit board such as an FPC board, miniaturization is obtained while reducing costs such as the mounting cost and material cost of the circuit board, and stable operation is performed. A liquid crystal panel (10) has a configuration in which jumper resistors (60a) to (60f) are provided in an overhanging portion (20a) of a glass substrate (20) to ground test terminals, which eliminates the need to ground the test terminals on an FPC board (50). Thus, wiring lines and connection terminals which are connected to the test terminals, respectively, and the numbers of which are equal to the number of the test terminals do not need to be provided on the FPC board (50), reducing the width of the FPC board (50).

Abstract: In a liquid crystal display device (10), stabilizing capacitors (61), bypass capacitors (62) and boosting capacitors (63), which would conventionally be mounted on an FPC board (50), are disposed along long and short input sides of an LSI chip (40) mounted on a projection (20a) of a glass substrate (20) and the capacitors are connected to their respective input terminals of the LSI chip (40) via capacitor traces (71). This makes it possible to narrow the FPC board (50) connected to the liquid crystal display device (10), thereby achieving size reduction of the liquid crystal display device (10) while achieving reduction in manufacturing cost, including processing and material cost of the FPC board (50).
