The display includes a display screen. The circuit board is located at a side of the display opposite the display screen. The housing is configured to house the display and the circuit board. The antenna is in the housing, and includes a communication portion and a ground portion. The shield is along a periphery of the ground portion in the housing, and is located between the antenna and the circuit board. ## Claims ### Claim 1 An electronic device comprising: a display device comprising a display screen; a circuit board located at a side of the display device opposite the display screen; a housing configured to house the display device and the circuit board; an antenna provided in the housing and comprising a communication portion and a ground portion; a shield provided along a periphery of the ground portion in the housing, and located between the antenna and the circuit board; a first wall provided in the housing, configured to have an electrical conductivity, and configured to cover the side of the display device opposite the display screen; and a second wall provided in the housing, configured to have an electrical conductivity, configured to cover the side of the display device opposite the display screen, and configured to be located between the display device and the first wall, wherein at least a part of the antenna is located between the first wall and the second wall, and the shield is provided in a bridging manner between the first wall and the second wall. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the shield comprises a projection projecting from a wall in the housing. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the shield comprises a member bonded with an electrically conductive adhesive to the wall of the housing. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein the circuit board is located near an end of the housing, and the antenna is located near a second end opposite the end. ### Claim 5 (depends on 4) The electronic device of claim 4, wherein the antenna is located near a corner located at an end in a lengthwise direction of the second end. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein the circuit board is located between the first wall and the second wall. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the shield comprises: a first portion configured to be provided at one of the first wall and the second wall and to have flexibility; and a second portion configured to be provided at other one of the first wall and the second wall, and to abut against the first portion. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the ground portion comprises a portion overlapping at least one of the first wall and the second wall, and the communication portion comprises a portion overlapping neither one of the first wall and the second wall. ### Claim 9 (depends on 8) The electronic device of claim 8, wherein the first wall comprises an opening, the opening is covered with a member having a lower electrical conductivity than that of the first wall, and the communication portion overlaps the member having the lower electrical conductivity than that of the first wall. ### Claim 10 An electronic device comprising: a display device comprising a display screen; a circuit board located at a side of the display device opposite the display screen; a housing configured to house the display device and the circuit board; an antenna provided in the housing and comprising a communication portion and a ground portion; a shield provided along a periphery of the ground portion in the housing, and located between the antenna and the circuit board; a first wall provided in the housing, configured to have an electrical conductivity, and configured to cover the side of the display device opposite the display screen; and a second wall provided in the housing, configured to have an electrical conductivity, configured to cover the side of the display device opposite the display screen, and configured to be located between the display device and the first wall, wherein at least a part of the antenna is located between the first wall and the second wall, and the shield is provided between the first wall and the second wall. ### Claim 11 An electronic device comprising: a display device comprising a display screen; a circuit board located at a side of the display device opposite the display screen; a housing configured to house the display device and the circuit board; an antenna provided in the housing; a shield provided along a periphery of the antenna, and located between the antenna and the circuit board; a first wall provided in the housing, and configured to have an electrical conductivity; and a second wall provided in the housing, configured to have an electrical conductivity, and provided with a space with respect to the first wall, wherein at least a part of the antenna is located between the first wall and the second wall, and the shield is provided between the first wall and the second wall. ### Claim 12 (depends on 11) The electronic device of claim 11, wherein the shield comprises a projection projecting from a wall in the housing. ### Claim 13 (depends on 11) The electronic device of claim 11, wherein the shield comprises a member bonded with an electrically conductive adhesive to the wall of the housing. ### Claim 14 (depends on 11) The electronic device of claim 11, wherein the circuit board is located near an end of the housing, and the antenna is located near a second end opposite the end. ### Claim 15 (depends on 14) The electronic device of claim 14, wherein the antenna is located near a corner located at an end in a lengthwise direction of the second end. ### Claim 16 (depends on 11) The electronic device of claim 11, wherein the circuit board is located between the first wall and the second wall. ### Claim 17 (depends on 11) The electronic device of claim 11, wherein the shield comprises: a first portion configured to be provided at one of the first wall and the second wall and to have flexibility;
