Disclosed is a bracket that allows a target object to be attached easily and prevents it from being detached unexpectedly after the attachment. A bracket (10) for attaching, to a wall surface, a television provided with locking pins (30) fixed thereto includes a back board section (11), an upper board section (13), a lower board section (15), and a front board section (14), the front board section (14) and the back board section (11) being separated from each other by a clearance that is large at an upper portion and small at a lower portion.

In a liquid crystal television device that is a wireless communication device, speaker storage sections are integrally formed with a main body section containing parts such as a liquid crystal panel section. Although the main body section is electromagnetically shielded, the speaker storage sections are not electromagnetically shielded. Antennas are provided along with speakers in speaker storage sections so as to have directions of installation different from each other by 90 degrees. This realizes a wireless communication device including an antenna structure capable of improving transmitting/receiving sensitivity in all directions.

In a liquid crystal television device (10) that is a wireless communication device, speaker storage sections (12a and 12b) are integrally formed with a main body section (11) containing parts such as a liquid crystal panel section (13). Although the main body section (11) is electromagnetically shielded, the speaker storage sections (12a and 12b) are not electromagnetically shielded. Antennas (15a and 15b) are provided along with speakers (14a and 14b) in speaker storage sections (12a and 12b) so as to have directions of installation different from each other by 90 degrees.

摘要:
Provided is a technique related to a thin display device having a frame structure in which accuracy is ensured. First and second restricting convex portions (84, 85) are formed on the inner parts of a bending hole portion (83). A restricting face (84a) which is an end portion of the first restricting convex portion (84) takes an angle of 45 degrees sloping from upper left to the lower right. A restricting face (85a) which is an end portion of the second restricting convex portion (85) takes an angle of 45 degrees sloping from upper right to lower left. When bending processing is performed, the restricting face (84a) of the first restricting convex portion (84) abuts against the restricting face (85a) of the second restricting projection portion (85).
