A phase difference film layered body is obtained by stretching a film before stretching, the film before stretching including: a P1 layer formed of a resin p1 containing polyphenylene ether having a positive intrinsic birefringence value and a polystyrene-based polymer having a negative intrinsic birefringence value and having a syndiotactic structure; and a P2 layer disposed in contact with the P1 layer and formed of a resin p2 containing an acrylic resin or an alicyclic structure-containing polymer. In the resin p1, the weight ratio of (the content of the polyphenylene ether)/(the content of the polystyrene-based polymer) is 35/65 to 45/55. A method for producing the phase difference film layered body and a method for producing a phase difference film using the phase difference film layered body are also provided.

An organic EL display device including a substrate, a transparent electrode, a luminescent layer, and a metal electrode layer in this order from a light emission side, a circularly polarizing plate disposed on the light emission side of the substrate, the circularly polarizing plate including a polarizing film and phase difference films that stacked on each other. The phase difference film includes a resin composition (A) containing polystyrene-based polymer having a syndiotactic structure and polyarylene ether, a ratio of the polystyrene-based polymer having the syndiotactic structure with respect to the polyarylene ether in the resin composition (A) is 65:35 to 55:45, being a weight ratio of (the polystyrene-based polymer having the syndiotactic structure) with respect to (the polyarylene ether), the phase difference film satisfies a relation Re&#x3c;Re&#x3c;Re, and an Nz coefficient of the phase difference film at a wavelength of 550 nm is &#x2212;0.25 to &#x2212;0.05.

Organic EL display device

A relay apparatus includes an external connection interface section and common terminal section. A plurality of communication sections are connected to the external connection interface section. The external connection interface section individually interfaces with the communication sections. The common terminal section is commonly provided for the communication sections and controls to perform communication by using one of the communication sections connected to the external connection interface section in accordance with operation by a user.

Relay apparatus

A mobile radiotelephone connecting apparatus and system by which mobile type telephone conversation can be realized using a network is disclosed. A plurality of groups each including a mobile radiotelephone set, a mobile radiotelephone connecting apparatus and a personal computer are connected to one another through a LAN. The mobile radio telephone connecting apparatus includes a Bluetooth interface for performing low-power radio communication, a LAN interface for establishing a connection to the LAN, a USB interface for establishing connection to the personal computer, and a CPU interposed among the mobile ratio telephone set, LAN and personal computer for allowing communication among the three.
