The present invention provides a novel naphthothiophene compound having a high lowest excited triplet level. Operations are executed on multiple functional units of a same type in the CPU. In another embodiment, a minimum playlist duration can be set as a multiple of a target duration which specifies a maximum duration of a media file specified in a playlist. Local image fields are defined along the curve and a field intensity is found for each by integrating the intensity of the image in the field. 2 \u03bcm or more and 15 \u03bcm or less. The invention prevents package warpage by providing the support layer, and allows disposing of other packages or electronic elements by electrically connecting the RDL structures through the conductive through hole vias.
