This backlight device (illumination device) is provided with (LEDs) light source; a light guide plate having a light-receiving face that opposes the LEDs and where light from the LEDs is incident, and a light-exiting surface where the incident light is emitted; and an optical sheet (optical member) arranged in opposition to the light-exiting surface of the light guide plate and imparting an optical effect to the light emitted from the light-exiting surface. Here, the optical sheet has, in at least one portion thereof, a chromaticity correction region for which x and y chromaticity coordinate values in a CIE 1931 color space both decrease with distance from the LEDs.

Illumination device and display device

The present invention includes, in addition to transistors each (Mm,n) provided at the intersection of a gate bus line (GLn) with a data bus line (DLm): block potential applying transistors (DMn) connected to respective ends of gate bus lines (GLn) which ends are not connected to a gate driver (); a potential supply line (VLL) connected to the gate bus lines (GLn) via the block potential applying transistors (DMn); and a blocking signal supplying section () for, immediately after the gate driver () supplies a first conduction signal for bringing the transistors (Mm,n) into conduction, supplying to the block potential applying transistors (DMn), a second conduction signal for bringing the block potential applying transistors (DMn) into conduction.
