A direct type back light includes a case holding a plurality of lamps. The lamps may be “U” shaped and have curves arranged at a centerline of the case to face each other with a gap there between. A reflecting plate is positioned below the plurality of lamps. A luminance control sheet is provided above the reflecting plate and below the lamps in several of, or all of, the gaps. The luminance control sheet may have a lower reflectivity or a higher reflectivity than the reflecting plate to remove a bright line or a dark line in the center of the display, respectively.

An electron emission device and an electron emission display, in which a driving electrode is protected from being damaged when an overcurrent instantly flows therein. The electron emission device includes a first driving electrode disposed on a plate, a second driving electrode disposed on the plate and insulated from the first driving electrode, and an electron emission portion connected to the first driving electrode. The electron emission portion emits electrons in response to a voltage difference between the first driving electrode and the second driving electrode. The second driving electrode has at least two separate portions, and the at least two separate portions are coupled to each other by at least one band having a predetermined width adapted to electrically isolate at least one portion of the second driving electrode from the electron emission portion when an overcurrent is applied between the second driving electrode and the electron emission portion.

Processing within a computing environment that supports pageable guests is facilitated. Processing is facilitated in many ways, including, but not limited to, associating guest and host state information with guest blocks of storage; maintaining the state information in control blocks in host memory; enabling the changing of states; and using the state information in management decisions. In one particular example, the guest state includes an indication of usefulness and importance of memory contents to the guest, and the host state reflects the ease of access to memory contents. The host and guest state information is used in managing memory of the host and/or guests.
