Definitions

  • inclined fixing portions 50 are formed on the upper side portion 41 of the intermediate chassis 40 at predetermined intervals.
  • the fixing portion 50 includes a base portion 51, a screwing opening 52, and an inclined rib 53 on the fixing surface 41 b.
  • the base portion 51 is formed substantially flush with the fixed surface 41b.
  • the base portion 51 may be integrated with the fixed surface 41b or may be configured separately.
  • the illustration shows a separated configuration.
  • the screwing opening 52 is an opening (a so-called fool hole) without a screw groove formed in the approximate center of the base portion 51.
  • the inclined rib 53 is formed on the upper surface of the base portion 51 so as to extend rearward so as to sandwich the screwing opening 52.
  • the inclined rib 53 has an inclination of a predetermined angle ⁇ with respect to the horizontal plane Lx so that the front side (display panel 11 side) is low and the rear side is high.
  • the fixing portion 50 including the inclined rib 53 is provided.
  • the shape of the fixed surface 241b of the intermediate chassis 240 is provided with an inclination.
  • the inner surface of the fixed surface 241b with respect to the panel arrangement surface 241a, that is, the surface in contact with the backlight chassis 14 is a horizontal plane Lh, as in the first embodiment.
  • the outer surface of the fixed surface 241 b, that is, the surface in contact with the side surface portion 22 of the front cabinet 20 is a surface Lx having a predetermined inclination angle ⁇ with respect to the horizontal plane Lx, like the inclined rib 53.
  • the backlight side surface portion 314b (the upper surface portion in the drawing) of the backlight chassis 314 is not a horizontal plane Lx but a plane having a predetermined inclination angle ⁇ with respect to the horizontal plane Lx.
  • the backlight back surface portion 314a has a predetermined shape on the assumption that the surface is parallel to the display panel 11.
  • the screw openings 29, 319, and 349 are fastened together by screws 90, and the side surface portion 22 of the front cabinet 20, the fixing surface 341b of the intermediate chassis 340, and the backlight side surface portion 314b are fastened together.

Abstract

L'écran plat ci-décrit comporte un châssis intermédiaire, un boîtier avant et un châssis de rétroéclairage (châssis de la surface arrière) assemblés à l'aide de vis latérales, son boîtier avant ne peut pas s'ouvrir de manière inopportune, et il évite les fuites de lumière. Dans un téléviseur LCD (10) faisant l'objet de l'invention, une surface d'alignement de panneau (41a) du châssis intermédiaire (40) est parallèle à un écran (11), et une surface de fixation (41b) est perpendiculaire audit écran (11). La surface d'alignement de panneau (41a) et la surface de fixation (41b) sont donc perpendiculaires. A cause d'une nervure oblique (53), sans laquelle la surface intérieure d'une section latérale (22) se trouverait dans un plan horizontal (Lh), ladite surface intérieure se trouve dans un plan (Lx) incliné à un certain angle (θ). Ainsi, une section avant (21) du corps principal subit une rotation dont l'ampleur correspond audit angle (θ), ce qui dévie son bord (21a) vers l'écran (11). Par conséquent, une vis (90) servant à la fixation peut aussi empêcher la section avant (21) du corps principal du boîtier avant (20) de s'ouvrir de manière inopportune.
