Abstract:
1. An organic EL display device, which stands for organic electro luminescence display device, comprising: a lower electrode provided every first organic EL element for a blue color and every second organic EL element for another color on a substrate; a partition layer in contact with said lower electrode; a hole injection/transport layer provided every first organic EL element and second organic EL element on said lower electrode, and having at least one of properties of hole injection and hole transport; a second organic light emitting layer for non-blue colors provided on said hole injection/transport layer for said second organic EL element; a connection layer made of a low-molecular material and provided over an entire surface of said hole injection/transport layer for said second organic light emitting layer and said first organic EL element, the partition layer extending from said lower electrode to be in contact with said connection layer, wherein a triplet excited state (T a first organic light emitting layer for a blue color provided over an entire surface of said connection layer so that the first organic light emitting layer for the blue color is above the second organic light emitting layer for non-blue colors; an electron injection/transport layer having at least one of the properties of the electron injection and the electron transport and an upper electrode provided over an entire surface of said organic light emitting layer in order.
