Lighting system and display device equipped with the same

A display apparatus, comprising:

• a display element that includes:
• scanning lines and data lines that are arranged in a matrix form;
• a switching element that is connected to each of the scanning lines and a corresponding one of the data lines;
• a pixel portion that performs a gradation display in accordance with a data signal written from the corresponding one of the data lines when the switching element is brought to an ON state based on a signal of the each of the scanning lines;
• and
• color filters that are arranged so as to correspond to the pixel portions and include at least filters of three colors that exhibit a white color when mixed;
• an illumination device that outputs plane-shaped light to the display element and includes a first light source that emits light of a first color that is one of the three colors and a second light source that emits light of a second color complementary to the first color, and in which each of the first light source and the second light source is a fluorescent tube having a cold cathode or a hot cathode, and an amount of light emitted by the first light source is smaller than an amount of light emitted by the second light source;
• a scanning line driving portion that sequentially supplies a selection signal to each of the scanning lines at a cycle of half a time period in which one image is displayed in the display element;
• a data line driving portion that, at one of a first half and a latter half of the time period in which one image is displayed in the display element, supplies a data signal to be written into each in a group of pixel portions among the pixel portions that corresponds to the color filter of the first color to a corresponding one of the data lines, and at an other of the first half and the latter half of the time period, supplies a data signal to be written into each in groups of pixel portions among the pixel portions that correspond respectively to the color filters of two colors among the three colors other than the first color to a corresponding one of the data lines;
• and
• a light source driving portion that, at the one of the first half and the latter half of the time period in which one image is displayed in the display element, switches on the first light source while switching off the second light source, and at the other of the first half and the latter half of the time period, switches on the second light source while switching off the first light source.
