Abstract: There is disclosed a lens frame structure having a movable lens holding frame, a shaft which guides movement of the lens holding frame and a support member which supports the shaft. Owing to an impact force applied to a lens frame, the lens holding frame and the support member are able to relatively move in an axial direction of the shaft to come in face contact with each other. At least a part of regions of the lens holding frame and the support member which come in face contact with each other are slant surfaces with respect to the shaft. Otherwise, the regions of the lens holding frame and the support member which come in face contact with each other can be a pair of a concave surfaces and a convex surface (a wedge surface, a curved surface, a conical surface or the like) substantially parallel to each other.

Abstract: At a writing time, a first transistor 412 is turned on so that a data signal Xj is supplied to one end of a capacitor 420. At this time, since a second transistor 414 is turned off, driving current does not flow to an organic light emitting diode (OLED) device 430. A power supply voltage Vdd is supplied to the other end of a capacitor through a power supply line L. However, since the driving current does not flow at the writing time, the power supply voltage Vdd is not reduced by the wiring line resistance of the power supply line L. On the other hand, at an emission time, the first transistor 412 is turned off and the second transistor 414 is turned on. Therefore, the driving current is supplied to the OLED device 430.

Abstract: The present invention provides an electro-optical device capable of achieving an increased light emission efficiency and an enhanced visibility. An organic electroluminescents (EL) display device has a plurality of material layers including a luminescent layer. In a plurality of material layers layered in the direction of light emission from the luminescent layer, first and second insulating interlayers are disposed between a substrate, which is positioned at the outermost surface, and the luminescent layer. The first and second insulating interlayers have a refractive index lower than that of the substrate. Accordingly, by forming predetermined materials having a low refractive index, the resulting low refractive index layers have a low dielectric constant, and consequently, the capacity between wires can be reduced.

Abstract: A lens barrel has a first group frame provided with a rotating frame having a cam groove and made of a synthetic resin and a cam follower made of a synthetic resin integrated with the circumferential face for relative movement with the rotating frame and engaged with the cam groove, in which a shaft member made of metal is inserted into the center portion of the cam follower. If the lens barrel is dropped and the first group frame undergoes a relatively large impact force, the impact force acts between the cam groove and the cam follower, but since the shaft member is inserted into the cam follower as mentioned above, breakage of a root portion of the cam follower is prevented, and since the cam groove and the cam follower are both resin, plastic deformation on the cam groove side is also prevented.
