Abstract: A first light emitting unit includes a hole injection layer, a first hole transport layer, and a first light emitting layer. A second light emitting unit includes a hole injection layer, a second hole transport layer, a third hole transport layer, a third hole transport layer, and a second light emitting layer. The second hole transport layer is formed on the hole injection layer and includes a first hole transporting material. The third hole transport layer is formed on the second hole transport layer and includes a second hole transporting material. A fourth hole transport layer is formed on the third hole transport layer and includes the same material as the second hole transport layer, that is, the second hole transporting material. The third hole transport layer is formed by using a coating method, and the fourth hole transport layer is formed by a vapor deposition method.

Abstract: A biological condition measurement apparatus has behavior condition detector (12) which detects the behavior condition of a mobile unit; mobile unit stable state determining member (17) which determines whether or not the mobile unit is in a stable state based on the behavior condition; biological condition detector (11) which detects the biological condition of the operator of the mobile unit; operator stable state determining member (17) which determines whether or not the operator is in a stable state based on the biological condition; and processor (15) which adopts biological information indicating the biological condition detected by the biological condition detector as valid biological information and executing at least one of analysis processing, record processing, and output processing of the biological information if it is determined that the mobile unit is in a stable state and that the operator is in a stable state.
