PROBLEM TO BE SOLVED: To effectively cool a light emitting device by a technology for suppressing temperature rise of the light emitting device. SOLUTION: A plurality of light emitting elements 24 are arranged in a plane form, on a surface of a base material 22 of a display panel 12. The base material 22 includes a first substrate 26 and a second substrate 28 which are connected together. A ditch section 32 is formed on an opposite face to the second substrate, of the first substrate 26, and a ditch section 34 is formed on an opposite face to the first substrate 26, of the second substrate 28. A tubular space surrounded by an inner face of the ditch section 32 and an inner face of the ditch section 34 is utilized as a flow path 30A of a coolant. The flow path 30A is unevenly distributed in a plane view, in a fixed pattern area P where a fixed pattern is displayed, in a display area A. COPYRIGHT: (C)2011,JPO&INPIT
