An electric optical apparatus including a display section in which an electric optical material is pinched between a pair of substrates and a plurality of pixels is arranged, wherein the display section is provided with a scanning line, a data line and a power-supply line that are connected to each of the pixels, and each of the pixels is provided with a pixel electrode, a driving transistor that is connected between the pixel electrode and the power-supply line, a capacitance for modulation that is connected between a gate of the driving transistor and the data line, a maintenance capacitance that connects one side electrode to the gate of the driving transistor, and a transistor for correction that is connected to a diode and in which one side terminal thereof is connected to the gate of the driving transistor.

A display device is for carrying out display by supplying a data signal, that is supplied from a video signal line, to one of a plurality of pixel electrodes via a switching element, and by supplying a scanning signal for controlling ON/OFF state of the switching element to the switching element via a scanning signal line that is orthogonal to the video signal line and is connected to the switching element. When the scanning signal is outputted to the scanning signal line, the scanning signal has a falling waveform that first falls substantially vertically from an ON-level of the switching element in a direction of an OFF-level of the switching element, and then starts falling with a slope, and again falls substantially vertically before reaching the OFF-level of the switching element. As such, the writing of the data signal to the pixel electrode may be securely carried out even when the writing period for each scanning signal is reduced, thereby displaying a high-quality image.

An image-correction-amount detecting device includes an image signal generation unit, a luminance detecting unit, and a correction value calculation unit. The image signal generation unit generates and supplies image signals having inverted polarities to a display section in which pixels are formed so as to correspond to intersections of a plurality of scanning lines and a plurality of source lines which are arranged in a matrix and which performs pixel display by allowing an image signal supplied to a source line to be applied to a pixel electrode of each pixel via switching elements, the image signal being supplied to the source line by turning on a switching element disposed in the pixel with the scanning signal supplied to the scanning line. The luminance detecting unit detects the luminance of each pixel position of an image displayed by the display section. While changing the reference voltage which is set in the display section, the correction value calculation unit calculates the difference of the luminance between a positive polarity image signal and a negative polarity image signal in each pixel position, calculates the distribution of reference voltages in the display section which applies the minimum luminance difference, and outputs an image correction amount to obtain the optimal reference voltage that matches the effective value of the positive polarity image signal with the effective value of the negative polarity image signal.

There are provided a display apparatus and a display method, with which compressed image data that is to be decompressed can be transmitted to the display apparatus in an environment in which a transmission capacity is not always secured, and good image display is realized. An example of the display apparatus is an active matrix display apparatus formed by using thin-film transistors formed on an insulating substrate. In the active matrix display apparatus, a circuit that receives an image data signal from an external system via a non-contact transmission path and amplifies the image data signal, a circuit that processes the image data signal, and a memory circuit that stores the processed image data are integrated on the insulating substrate.

When a video signal type detecting section detects a video signal of PAL/SECAM (50 Hz) video signal, the input image data is subjected to enhancing conversion with a degree lower than the degree of enhancing conversion in the case of NTSC (60 Hz). With this, the response speed of liquid crystal is improved and an image noise on account of excessive enhancement is eliminated, so that the deterioration in image quality is prevented. As a result, the enhancing conversion with respect to the input image data is performed in such a manner as to compensate the optical characteristics of the liquid crystal display panel, and an image noise on account of excessive enhancing conversion with respect to PAL/SECAM (50 Hz) image data, and hence high-quality image display is realized.

A liquid crystal display device prevents the gray level folding in at least one of the vicinities of the highest and lowest gray levels while avoiding the complication of the data line driver circuit. The data line driver circuit generates output voltages whose number is equal to a predetermined gray level number M based on reference voltages, and selects one of the output voltages and outputs the selected one to the display section in response to an inputted image signal, thereby displaying images The applied voltage-brightness characteristic of the display section has a zero brightness change region in which the reference voltage corresponding to the highest gray level is located. The reference voltage corresponding to the next lower level to the highest level is set such that the brightness at the next lower level is lower than that at the highest level by a predetermined difference.
