An active matrix substrate includes a plurality of pixel electrodes; a plurality of switching elements that connect to each of the plurality of pixel electrodes; a plurality of pixel lines that connect to each of the plurality of switching elements; a plurality of connection lines that connect to each of the plurality of pixel lines; and a plurality of terminals that connect to each of the plurality of connection lines. An arrangement direction of the pixel lines and an arrangement direction of the terminals differ.

Active matrix substrate, liquid crystal display device, self-luminous display device, and imaging device

Provided are a backlight unit and a liquid crystal display device. The backlight unit includes: one or plural LED light sources including N-colored LEDs; a photo-detecting section which measures light intensities of red, green and blue colors of received light and outputs corresponding signals; a driver section including N LED-drivers; and a control section including a drive-condition calculating section and a memory. The drive-condition calculating section calculates control signals for three colors among the N colors, on the basis of information stored in the memory and the signals outputted by the photo-detecting section, makes a pair of each remaining color and one of the three colors, outputs the control signals for three colors to the corresponding three LED drivers, and outputs a control signal determined by using the control signal for a color paired with each remaining color to the LED driver for the each remaining color.

Backlight unit and liquid crystal display device

A direct type LED backlight device improves color unevenness on the periphery of the display region without increase of the driver and its control circuit and contour change of a liquid crystal panel. This device includes a bottom wall, a set of optical members arranged opposite to an inner surface of the bottom wall, a side wall maintaining the bottom wall and the set of optical members at a predetermined distance, and LEDs fixed to the inner surface of the bottom wall. The side wall has a protrusion protruding toward a central portion of a space formed by the bottom wall, the side wall, and the set of optical members. At least part of emission surfaces of the LEDs arranged at outermost positions are overlapped with the protrusion and located at such positions as to be invisible when seen along a direction perpendicular to the set of optical members.
